EXCERPT FROM MISSING LYNX - Book Two

We watched the monitor closely; the robot stood flush with the case. A pincer reached out to twirl the locking system, using the combination that I had uncovered while behind the Veil. The mechanical arm moved with amazing dexterity, slowly releasing the catch, retrieving the papers and files. Axel wiggled the toggle and the robot zipped back to us with the booty. Again Axel maneuvered the machine to the case. The robot sent a video image to our laptop; I studied the screen until I could show Axel where the concealed latch protected the hidden compartment. We all held our breath while Axel maneuvered the motorized claw to release the hook.

The following information was gathered from bomb squad members that I met at this year's Writers' Police Academy. Because of their undercover work, neither their names nor images can be used in this article. A bomb squad member is also called an EOD (Explosive Ordinance Disposal) Technician. All EOD Techs come through the Redstone Arsenal in Huntsville, Alabama where they undergo an intensive 6 week training session.
* There are at least two people per responding team.
* Typically this team prefers nine members
* On this team, the EOD techs have other police duties and leave those duties to respond to bomb threats.

The Suit

Bomb Protective Suit is a little bit of a misnomer. Though it can help; it will not actually keep someone alive under all circumstances. What makes a difference in survivability?
* How close is the officer?
* How big is the blast? The concussion of the blast can be as deadly as the shrapnel.
* At five feet from the bomb survivability increases by 50%

I am all suited up at the Writers' Police Academy 2013

I'd explain this to you, but then I'd...  EOD Suit WPA 2013

  blast concussion.
* Cost? aprox 75k
* The suit weighs approximately 85-100 lbs.
   35 lbs for the trousers
   35 lbs. for the jacket
   8 lbs. for the helmet
   And boots.
   This suits allows little in the way of dexterity and
    agility. More armor might increase protection 
    but make movement impossible.
   (Though this guy is going to prove me wrong: VIDEO QUICK STUDY - dancing in a EOD suit 2:17)
   * The helmet includes a fan unit to help prevent  humidity from building up inside of the visor. But
      does not cool the person inside.
   * The suit has no cooling unit - considering the  weight of the suit, the body response to adrenaline and 
       physical activity, and the ambient temperature a bomb technician has about a twenty minute window
       of operational opportunity. 
   * If there is a possibility of a contaminant or bio-hazard, the team members have access to special suits
      that incorporate oxygen tanks (SCBA Self-contained Breathing Apparatus). These tanks add to the
      weight and loss of agility. These usually have about 45 minutes of air. That time period must include time 
      to "decon" (decontaminate).

TOOLS-
VIDEO QUICK STUDY - Tools in use (3:53)
1. Telescopic manipulator - has a claw allowing a technician to work from a safer distance.
2. Ordinance disposal tools - the one we saw was approx. 35 lbs and could shoot the bomb. Also, there
    are:
   * robots with hooks, arms, car door openers, etc.
   * water jet disruptors

   * laser aiming devices, and so forth.
3. Remote viewing systems that might include
  * Borescopes
  * Videoscopes
  * Fiberscopes
  * X-ray technology 
4. Disruptors - can open up the package.
5. Bomb Detection Dogs
    VIDEO QUICK STUDY (2:32) 
   * Dogs are typically taught to sit or lie down when
      they detect the scent.
   * Typically they are rewarded with a ball
   * Dogs are trained to the base component of
      explosives. Once they have these components
      any combination will trigger an alert. Dogs smell
      differently than humans if a human smells "stew," a
       dog  smells carrots, and beef and onion, etc.

WPA 2013 That's my scary  backpack.
 I named the robot  "Molly," because she needed a name.

6. Robots - 
   * Cost? Approx 125K and up
   * Depending on model, these are around 44 lbs.
   * VIDEO QUICK STUDY (3:41) 
     THIS IS EXCELLENT
   * Major issue is depth perception. That's
      why these techs practice, practice,
      practice.
   * Information is transmitted via wireless to
      the  HAZMAT truck

ASSESS, ASSESS, ASSESS
Video Quick Study British EOD Tech talking about the "Long Walk" and assessment  (2:38)
For a bomb to go off there need to be three components:

1. Battery

2. Switch

3. High Explosive Charge

Disrupt any of these and you render the bomb inoperable.

Basic Techniques

(Techniques are kept secret so as not to train the attacker in better ways to succeed)
VIDEO QUICK STUDY - Suspicious Package Investigation (9:02)
1. Determine that there is a possible event. In the case of the technicians I was interviewing, most of their
    calls come from people who have found dynamite, or war souvenirs (WWII from granddad) and not
    from actual concerns about a bomb.

WPA 2013 Bomb Extraction Truck

2. Bring in the team and their trucks
   * Mobile Headquarters with gear also called
      HAZMAT Truck
   * Containment Truck
   * EMTs and fire
3. Clear the area to ensure the public's safety
   * Set up equipment this might include tenting if
      they believe bio-hazardous materials were
      used.
4. Suit up
5. Develop intelligence
   * They cannot use radio communication because it could set off the bomb.
6. Formulate a plan
7. Work the plan and leave.
   * If they are exploding something they yell, "FIRE IN THE HOLE!" three times.
   * Exploding the object is called "disrupting the device."
   * Counter Charge - means to put another explosive device on top of the suspected bomb and blow it up

Forensic Toxicology - Drugs and Poisons 101: Information for Writers

___________________________________________________________________________________

Excerpt WEAKEST LYNX

       I undressed in the bathroom. When I lifted the hamper lid, my peripheral vision caught a dark face reflected in the mirror. I gasped, my brain processing like a camera with an open shutter. Click. Tribal tattoos. Click. Gas mask. Click. Sink on right. Click. White cloth. Click. Sweet odor. Click. No alarm. Click. No help.

       While my mind snapped perceptions, my body acted from training. I lowered my hips to drop my weight for better balance and leverage. My left leg swung behind his. I bent my knee in a swift, sharp move as I reached over my head, grasping his shirt to put him on the floor.

        But the initial fumes I had sucked in made the room watery and undulating, melting my muscles and my instincts into useless puddles. My arms dropped ineffectually to my sides. One of his hands trapped me against him as I dangled, unable to hold my weight up with my legs, while his other hand smashed the cloth tightly over my nose.

Forensic Toxicologists study how animals are affected by drugs and poisons. They work for various independent companies as well as agencies.

Inside a forensic department there are typically two chemistry labs housed in different locations because of the potential for cross-contamination. There are:
1 Contraband Substances Labs
* Identifies substances in seized form
* Typically measured in gram and kilograms
2 Toxicology Lab
* Identifies substances that are found in urine, blood, and tissues
* Typically measured in micro-gram and nano-grams
What is a Forensic Toxicologist (1:50)

Some Useful Vocabulary:
A drug - single chemical or compound chemical that has psychological and or physical reactions on the

   body.
* Prescription
* Over the counter
* Recreational
   legal - such as alcohol
   illegal - such as heroine
* Natural - such as caffeine

A poison has life threatening 
                effects.
Toxicology - The study of how humans and animals are
                affected by poisons or drugs
Forensic Toxicology - how the affect of drugs and
                 poisons have legal ramifications
Synergism - Forensic Toxicologist must be mindful
                  of Synergism - When two or more drugs or
                  substances work together to increase the effect such as
                  alcohol and barbiturates. Jimmy Hendricks, Janice
                  Joplin are two examples.
Pharmacologyy - the science of understanding the way drugs act
                  and the affects they have on a body
Pharmoketetics study of how drugs move - including how they get
                  into and out of the body
Absorption - how a drug gets into a body 
                        VIDEO QUICK STUDY Absorption and Dose (7:49)

 1. The drug can be inserted intravenously - shot directly into a
      vein/ the blood system. They can also be shot into a muscle 
      where they will enter the blood in a gradual manner.
 2. Orally - entering the body through the digestive tract
 3. Rectal insertion - crossing the mucus lining into the gastro-
     intenstinal tract
 4. Inhaled - such as for asthmatics or with a nebulizer or gas like
     carbon monoxide poisoning.
 5. Deramal - lotions and other products that are applied to the skin,
     but will not typically show up in significant quantities in the
     blood stream.
 6. Ocular

Distribution - almost always the product is distributed to the rest
     of the body through the blood/circulatory system. These do not
     circulate in an even way.
 1. The heart and liver - often have a higher concentration
 2. The brain - many drugs cannot get into the brain because blood
     networks in the brain are less permeable than other parts of the 
     body.
 3. Some products simply build up in the system. Pesticides, for
     example, build up in fatty tissues (adipose) over time. 
     Example of this is mercury in fish.

Metabolism - (broken down into metabolites) usually happens in
      the liver.
 1. Drug is deactivated with time.
 2. Body eliminates the drug
 3. Converts it into a substance that can be used for energy

Elimination - 
  1. Most is removed through urine (that's why urine testing is so 
      important)
  2. Feces
  3. Sweat
  4. Lactation
  5. Hair follicles.

Poisonings can occur by:

Accident

•   Child poisoning
•   Storing improperly, putting a poison in an incorrect 
•   Container/mislabeling
•   Taking the wrong medication
•   Taking one's medication multiple times during the day (do     to dementia, etc.)

  Adverse drug interactions

•  An individual might have specific issues such as organ    damage that is exacerbated over time by taking certain     medications.
•  Environmental causes such as radon or industrial chemicals
•  Animals such as spiders or snakes
•  Plants

  Overdose on recreational drugs VIDEO QUICK STUDY of street drugs and their forensic effects (9:52)

Suicide only fatal about 2% of the time but often results in organ 
             damage.
Homicide

In a living person signs of poisoning might include:

• nausea and vomiting
• respiratory distress
• change in skin coloration
• seizures
• blurred vision
• slurred speech
• mental confusion
• swelling
• Loss of consciousness

The severity of the reaction depends on many factors including:

•  Size of the victim
•  Health of the victim
•  Amount of substance
•  Duration of exposure

When deciding if this was a suicide or homicide investigators may utilize a forensic psychologist or death investigator to interview family, friends, and coworkers to put together a picture of their health  history, their state of mental health, and their history of drug use both legal and illegal.

Tests can be performed on the living or the dead.
Subjects who are living might be tested for some of these reasons:

•  Pre-employment drug tests
•  Randomized drug testing for public safety
•  Athletes
•  Crime scene - was a suspect under the influence?
•  Victim of a crime - for example was a date rape drug used?

   Blog - How to Drug Your Victim - the Four Main Date Rape Drugs

Post-mortem Forensic Drug Tests are done by Forensic Toxicologist and/or Forensic Pathologist - medical doctors specializing in disease and chemistry.

In trying to determine the poison/toxin there are three main steps:

Sample - Postmortem Sampling List will probably look at:

•       blood
•       urine
•       stomach contents
•       bile and liver (site of metabolism for many drugs)
•       brain tissue/spinal fluid
•       vitreous fluid (from the eye) Even in a body that has                  already started to breakdown, this is often a place where             toxicologists can gather information because the eye is               more resistant than other tissues to decomposition.

•       fatty deposits
•       hair - this is the longest lasting           source of a decomposed body.

Screen -
      * indicates a drug might be present
      * some drugs mimic naturally 
         occurring substance
      * Gas Chromotography VIDEO QUICK STUDY (1:12)
      * Enzyme Multiplied Immunoassay Testing
         VIDEO QUICK STUDY (2:06)
Extract -
     * concentrates the drug so it's easier to detect
     * removes other substances that might contaminate the results
     * Mass Spectometry VIDEO QUICK STUDY (7:59)
       qualitative and quantitative information is gathered

The Man Had His Penis in His Hand - How NOT to leave dance class.

___________________________________________________________________________________

 (Photo credit: useless no more)

I know I usually post on Mondays, but something happened last night, and I thought that I needed to share this with you all, in the hopes that beyond using the information to write a good scene, maybe it will help someone stay safe.

I'm just going to tell you the story, then I'll break it down and give you some insights.

Last night fairly late, tired and ready for the day to be over, I left the dance studio with my daughter, and her medical alert dog, T. My arms were full. I had T. on his lead, his "place" which is a large quilted pad, my backpack with my computer in it, and my car keys. I moved into the parking lot with my teen yammering about her costume fitting, walking behind me. We walked toward my mini-van that was parked nose in on the side of the lot next to the woods.

As we moved forward, away from the studio and the lights, my focus was on a man that I saw easing quietly to the side of my van. I stopped short. I hadn't seen him move into the woods. There was a large black truck in the driving space just to my left. I gave myself a second to assess. Did the truck belong with that man? The truck's door popped open, and I took a step back to gain distance. I immediately recognized the man emerging as one of the other dancers' fathers.
      "Where'd he go?" he asked.
      "To the right. The light hasn't come on, so he's not in my vehicle."
We moved cautiously together to see. And there was the stranger in all of his glory, leaning against my door, 6'4", out of his freaking mind on some drug, penis in hand.
      At that point I wanted out of there. I hand unlocked the door, shoved everything in, including my kid and her dog. I hit the lock button and peeled out of there with Crazy-man holding on to my door handle and explaining to me about his penis in a very loud voice. I had a window-breaker, a very nasty tool that would easily crack a skull, in my hand by this point and thought,  "Wow, I'm doing everything wrong."
      I drove home and had a rum and coke.

This did not go well. And as a trainer, I would say I did not perform well. I want to break this down so if this is you, you can do better than I did. And if this is your character? Well, good luck to her.

Parking Lot at Night (Photo credit: VinceFL)

1. I ALWAYS park pointing
   outward, (first mistake was to
   break my rule) because in an
   emergency
   you don't want to be backing up
   (ask my friend Cathy who blared
   her horn, so I didn't smash into her
   new car in my haste).
2. Park under a light/camera and
    away from landscaping that can
    obscure your view.
3. No matter how tired and
    distracted you are, you must
    remain vigilant. I make a habit of
    scanning every time I'm out in
    public. For decades I have been
   scanning, but this night, it made the
   difference. My daughter didn't
   walk, alone, around to the passenger side to find the crazy man with his dick in his hands when mom was
   out of reach.
4. Develop a strong arm. Your non-dominant arm should have your carried items, your keys should be easily
   accessible, and your weapon should be in your dominant hand. I have several blog articles about weapons
   that are easy to carry, as well as their pros and cons.
   * Kuboton
   * Asp batton
   * Stun Guns and Tasers
   * Pepper Spray and Mace
   * Conceal carrying a gun
5. Move with focus to your car. Everyone in, doors locked immediately, and pull out. This is not the time to
   text and read mail etc.

What does it mean to move with focus?

Parking Lot at Night (Photo credit: David H. Chu)

1. Scan the area to get a good feel for who is there and
    who is moving in a way that your paths will cross.

2. Be aware of the cars that are parked beside you.
    If someone is sitting in the passenger seat next to
    your driver's door, you may want to get in from
    your passenger side or go get someone to escort
    you.
3. Be aware if the cars beside you, or your car
    allows enough space for someone to easily lie
    underneath. Glance under the vehicles as you
    approach.
3. Briefly check the floor boards front and back for
    unexpected visitors. and get in quickly.

God forbid something go wrong for you, but if someone tries to abduct you in the parking lot here is a LINK with some strategies.

As you drive home, be aware if anyone is following you. This happened to me once, so I drove an extra block and visited the fire station.

Now as you go through a list of possible weapons, everything from concealed guns to knives, from electronic weapons to mace, you may feel uncomfortable with any or all of them. Babies in arms, curious children, and pets, as well as a willingness to use a weapon and having the training to do so effectively come into play.

At night, I am now carrying (except for last night - when it would have been the perfect weapon) a high powered handheld (4") flashlight with enough lumens to blind a person if it is dark outside.
* A lumen is simply the measurement of a light's brightness.
* A high-powered tactical flashlight is easy to find on the web. I happen to use Autocraft.
* In a dark environment, the light is intense enough to blind someone. They cannot see past the light to know
   what you are doing. It is disorienting and gives you an authoritative posture.

Your number one weapon is your awareness and focus.

Your number two weapon is your posture and your voice quality 

Though maybe yelling at the guy, "Hey! Get off my car!" was not the very best tactic. The best tactic at that point was to back away and go to the studio to call the police. But hey, hind-sight...

Aggressive Body Language 101

And it's always good to have a physical weapon at the ready, something you are comfortable with deploying be it a high pitched siren or bear spray.

The dance school owners did call the police. When the cops arrived, they found the guy with his pants around his ankles, his shirt pulled up, lying in my parking spot, rubbing his belly next to a pile of poop. The crazy guy spent the rest of the night in jail.

Please let me know if you have any questions, and I will do my best to help.

Investigation, Interview, & Interrogation: Information for Writers

____________________________________________

EXCERPT FROM CHAIN LYNX

    “T-bone don’t matter none. He in for assault. He a gang banger. No one believe nothing he’d say. He want to tell? Go ahead. He just trying to trade me in for a free walk, man.” Hector rested his eyes on his knees.
     “You told T-bone your story.”
     Hector looked up at Axel and back down with a scornful huff.
     “And now T-bone is dead,” Axel said.

     Hector all but threw his body out of his chair. He moved back in the tiny interrogation room, away from Axel, to stand in the corner. He was cornered.
     “What you mean T-bone dead?”
     Axel said nothing.
     "He was alive this morning when I got moved.”
     Axel gave a slight nod.
     Hector stalked back to his chair, sat down, and leaned
forward, tightly wound, focused. “T-bone dead?”
     “This is bigger than you could ever imagine.” Axel’s voice was quiet. Eerily free of emotion. “You are smaller than you could ever imagine. You, Hector, are a bug under someone’s shoe, and you are about to get squashed. I want to know why.”

While intelligence gathering happens prior to a crime, an investigation happens as a reaction to a crime.
It is important for a writer to understand the different roles that are played by investigative professionals.
A forensic scientist processes evidence. Unlike what we see on TV, forensic scientists usually DO NOT conduct interviews or interrogations. Typically interviews and interrogation are considered police science rather than forensic science.

An interview is conducted with a witness and an interrogation is conducted with a suspect.

*Police interviews happen anywhere - on the street or in the station.
*It is important to note that people can reply or not.
*In an interrogation, suspects have the right to protect themselves from self-incrimination.
*Witnesses have the choice whether to cooperate or not.
*Even though witnesses can refuse to talk, they can be compelled to disclose their information in front of a
  grand jury and other court hearings. If an investigator is talking to someone who is refusing information, they
  can be threatened with a subpoena.

As a writer, you'll want to consider:

*Does the investigator have jurisdiction?
  Lee Loftland's blog about which agencies conduct which kinds of investigations
*What if several agencies can claim jurisdiction? Typically the location with the most significant crime
  and the best case will take the lead. This can cause problems and might help with your plot twists.

(Photo credit: Wikipedia)

Investigations begin once it has been determined that a crime has taken place by one of the following:

*Police
*Prosecuters Office
*Grand Jury

Investigations can be broken down into three types:

1. Administrative - These are fact finding inquiries within an agency or business
*Professional Misconduct
*Safety Violations
*Employee background checks

(Photo credit: Wikipedia)

*Harassment
*Discrimination
Video Quick Study - Investigators' Reports (4:21 Industry Investigator)

2. Criminal Investigation - conducted by an agency

3. Private Investigation - Professionals hired from
    outside of agencies to counter what the agencies
    produce for evidence

Once an agency decides that a criminal act has taken place two things must occur:

1 - Find the suspect
2 - Connect the suspect to the victim and the crime. This includes forensics, interrogation, and interviews

Study Links to Related Blog Posts :

To reach the goal of arrest and conviction, investigators use:
* Search Warrants
* Arrest Warrants
* Forensic science applications
* Interviews
    Study Link: How a Police Sketch Artist Works
* Interrogations
   Study Link: Body Language of Liars
 
An interviewer will ask the same questions that your readers want to unravel as they read your story. Just remember Kiplings "Six Honest Men." Who? What? Where? When? Why? and How?

Some things for a writer to consider about their witness:

* What was the motive for coming forward?

At the Writers' Police Academy. I confess!

* What was their vantage point?
* What is their emotional state?
* What was their physical state?
* Were they injured? In shock?
* Were they under the influence of drugs or
   alcohol?
* Are they very old, or known to have impaired
   memory?
* Are they very young?
   Video of a child being interrogated. (8:00)
* Does the witness have limited intelligence.
* How long ago did the crime happen?
* Are the witnesses afraid to offer their
   information? - Perhaps your witness is afraid of
   the police
   because of something that has happened in the past. (Blog link showing this concept in action),
   or they are afraid of what might happen to themselves or their family and property if they step-forward
   with information.
   As a writer, if you have a character who is a reluctant witness, you might choose for them to use
   an anonymous tip line to get the information to the investigators.
* Perhaps your witness just doesn't want to get involved - they think that it would take time away from work
   or they would have to go to trial etc.

The investigator will use standardized forms to document the information. These may include:

* Witness Investigation Reports
* Missing, Damaged, or Stolen Property Reports

The Interview and/or Interrogation

Psychological studies have been conducted to try to get the optimal amount of information from a witness. To this end police might choose different locations for their interview. The police may walk the witness through the crime scene. They might conduct the interview at the home. Or possibly bring them in for formal interviewing at the police station.

Video Quick Study
First Jodi Arias Interrogation go to mark 3:00 to see her commenting on the temperature and watch the friendly, helpful tone of the investigator.
Training an Investigator (21:06) Talks about all of the things that impact and develop in an interview or interrogation (this focuses on child interviews) very interesting what technology has been developed for training purposes and beyond.

A writer must decide how this is documented either on camera or just voice recorded. Typically the investigator will put the recording device on the table in front of the witness. Being voice recorded is by consent-only in most states. A video tape, however, does not need to be disclosed if it is visual only. Often it is NOT disclosed that video is being taken because this has proven to impede the interview. Perhaps you want the witness to have this added intimidation factor? Perhaps you choose not to include video and something important is missed and the suspect is set free?

Sometimes a witness interview changes into an interrogation. If this happens, the subject will need to be apprised of their rights to not implicate themselves in a crime. Custodial Interrogations - the suspect is arrested then interrogated this is done AFTER their Miranda Rights are read to them.

*Typically only one person conducts the interview or interrogation.
*Forensic scientists DO NOT conduct interviews or interrogations.
*Investigators are trained to use a soft, normal tone and have a friendly demeanor.
*Typically at the beginning of an interrogation, time is spent just getting to know the person, figuring out the
  subject's capacity intellectually, and psychologically - how competent are they?

Human Memory and Eye Witness Accounts - Information for Writers

______________________________________________________
                                                                                    

Excerpt from WEAKEST LYNX -

     “Wilson’s stable. In police custody at Suburban. He’s being charged with breaking and entering with intent to harm, and possession.”

     I waited for the rest of the charges.

     Striker pursed his lips.

     “Wait. What about six murders and an attempted murder?” My voice squeaked.

     “The D.A. is having trouble putting together a case. The original six were linked to you by the MO. We have no evidence. None. Though they’ve been working on developing the case since your attack.”

     “But what about me? I saw him. The neighbors saw him. We confirmed the police sketch. Surely…”

     “Subsequent to seeing him, you sustained a traumatic brain injury. The defense can shred your eye-witness report on the witness stand. Same with the neighbors. They were running in the dark. Could be a look alike. There were no prints, no DNA, no motive linking you two. They need something more or they can’t make the case.”

THE INNOCENCE PROJECT "Many wrongful convictions overturned with DNA testing involve multiple causes: 75% involve eyewitness misidentification... Prosecutorial misconduct, ineffective defense, police misconduct and racism are harder to quantify but were also factors in many of the wrongful convictions that have been overturned with DNA testing." 

75% of wrongful convictions involved eyewitness misidentification? How is this possible?

The first thing that needs to be understood about memory is that humans do not process events like a video recorder. We process information based on focus, intensity, and past experiences. 

All of our individual past experiences form "schema" in our memory banks. As we encounter information our brain looks into its schema-files and develops an understanding based on what it has experienced before.

(LINK to a guest blog demonstrating the impact of past schema on present situation) 

When one remembers an incident the various past schema can overlap and mingle. The witness memory can be crystal clear - but it might not be the reality of what took place.

The Four Types of Memory

* Cognitive - These are sequences and patterns.
* Motor Vestibular -Body memories such as
   playing a instrument or driving a car
* Emotional/Affective - These are memories of
   feelings like grief and fear.
* State - These are memories from the senses. State
   memories seem to be the most helpful in developing
   a  clear picture of what occurred. PTSD plays from
   this memory - a certain smell or noise can trigger a
   physical reaction. Auditory memories are less reliable than visual
   memory. But  as a plot twist, an author should understand that
   witnesses are more confident in what they hear than what they
   see.

The Stages of Memory 

 (Photo credit: Wikipedia)

* Short Term - Unimportant data that is processed in the now. If
   the brain deems something to be important it moves the
    information into long term memory.        

* Long Term - Can be retrieved from past events. One's ability to
   recall depends on how information was processed. Processing
   depends on which of the four types of memories or which
   combination were used to interpret and "cluster" (this is basically
   a filing system).

The more significance-in-the-moment and the more types of memories involved create the clearest and most accurate memory picture. As a writer, think about your character. As she remembers something, which of her memory types is she using? For example, does she cognitively recall the fear that slowed her sequence of her actions when she smelled the smoke? Could she be making a profound mistake because she clustered the schema and now has a faulty memory? Did she remember the man saying, "I will kill you!" when she was really merging the event with a nightmare she had had just the night before?  

Remember that no two people could ever remember an event from the same perspective. It's just not possible. What if your characters had completely different memory schemas of an event? Wow - all hell could break loose!

So we know that people will perceive with four different kinds of memory. They will either store in their long term memory, or not. They will develop a schema based on their past experiences and cluster these in their memory banks. But what are some of the components that might interfere in a clear and accurate memory? 

A list of possibilities:

* Beliefs

* Stress levels

* Cross Racial Identification Bias
   Brains are wired to identify distinctions in our own
   race but NOT other  races. 

* Distinctive Aspects - People will remember
   particularly attractive or especially unattractive
   physicality better than "average" looks.

* Age of Witness - Children and elderly are less
  accurate and their descriptors might be different as
  well. Example: to a five year old "really old" could
  mean someone who is in their thirties.

* Gender - Men and women remember different
   aspects because of how their brains are wired. A
   man, for example, might remember the make and
   year of a car while a woman might remember that

   it was blue.

* Profession - Ex. an artist might have a better ability
   to recall the face structure while a physical
   therapist might notice a posture or unusual gait.    

* Drug or Alcohol Use

* Head Trauma - As in the excerpt from Weakest
   Lynx

* Weapons Focus Effect-If there is a weapon present
   the witness focus remains on the weapon (duh) and
   not on anything else in the environment.
   (LINK - Blog about my experience as a eye witness
     in a simulation)

* Attention - A victim or bystander will pay more
   attention to details if they are aware of what is happening
   than someone who is not aware that something is going on. Even
   if the witnesses are very attentive and good with faces, it is hard
   to find the words to describe a person. Try this experiment - think
   of someone you know very well, now try to describe out loud
   their features so that someone could draw them
   (Witness recall and Police Sketch Artists)

* Setting - Full day light, face full on, length of time of incident
   and time when recalled. 20 min can cause a sharp decrease in the
   number things that can be remembered.

* System Variables - These are police and legal procedures that
   can introduce bias.

In the 1977 Supreme Court decision in Manson v Brathwaite (Information Link)  - It was determined that eyewitnesses are allowed to testify if they are very sure of testimony. If they are unsure it is up to the judge in the case whether to allow or not. Psychological studies have shown that the degree of certainty does not correlate with accuracy. 

Many countries realized that innocent people were going to jail based on false witness memory - remember the witnesses can be 100% sure of themselves. They are not in any way "bad"; it is the way that memory works that makes eye witness testimony so very difficult. In 1999, Janet Reno was tasked with trying to develop procedures to help prevent some of these false-memory reports.

If your book takes place AFTER 1999, it should reflect these changes:

* Police ask open ended questions. Instead of asking, "Did he have
   a gun?" thus planting the memory of a gun, the police should ask,
   "Do you remember a weapon of any kind?"

Memory (4:20)
VIDEO QUICK STUDY Misinformation Effect (3:46) How questions effect recall

* Police should pause before asking another question, giving the
   witness a chance to think about a situation and perhaps remember
   another detail - This is one I used a lot in my counseling practice:
   Ask. Answer. Wait.

* The police should inform the witness that they can say, "I don't
   know." This helps to prevent the witness from trying to fill in the
   blank with information that is being pulled from a different
   schema.

* The police, when possible, should physically walk the witness
   through the crime scene. This might trigger memories from the 
   "state" memory bank.

* Careful use of Police Lineups - A line up, either in person or with
   photos, should be done in a double-blind scenario. The officers 
   who are conducting the lineup should not know who the suspect
   is. This stops the voice inflection and body language tells that are
   picked up by the brain of the witness ex. "Are you sure that's the 
   right guy?

         students were extremely sure of

         themselves and would have, under the Supreme Court ruling, 
         been allowed to testify. Watch their faces

         as every single one of them realizes that they were wrong.

Relative Judgement - when a witness tries to pick the person who most closely aligns with the memory of that person. To prevent the witness from feeling that they HAVE to make an identification the officers should say that the subject MAY or MAY NOT be in the lineup. Also, the members in the lineup should be presented sequentially one after the other and one at a time. Witness will compare the suspect to the mental picture and not use relative judgement.

Fillers - the other people in the line-up should look similar. If         the suspect had dreadlocks then the fillers should have dreadlocks. If the witness picks a filler, then it should be noted that their recall

might be questionable.

How can your heroine help?

During a crime the heroine could look for anything that is unique and difficult to shed or change such as:

        * Body-type (height, weight), tattoos, scars, focus on ears and
           nose.

        * Movement - limps, postures

        * Voice - lisps, unusual accents or speech patterns

As soon as possible - and without talking to ANYONE ELSE the heroine should sit down and write down all of  the details that she can recall - She could write them, sketch them, or even call and leave a message recording so she can retrieve the information later.
