Is It Harder To Write Crime Fiction Today? Notes:

Do modern forensic science and police investigative techniques make creating compelling crime fiction more difficult? Are there simply too many balls to keep in the air? Too much to consider? Or is now little different from then?

The Past, the present, and the future

Forensic Science timeline—-a fairly new discipline

Basic Science, then Medicine, finally forensic science

Personal ID

Visual
Bertillon
West Case
Facial recognition
Behavioral Profiling

Prints, ABO type, DNA, DNA Phenotype

Fingerprints—-then and now

Vucetich—the Rojas case
Stella Nickell Case
Touch DNA
Touch Toxicology

Toxicology

From arsenic to GC/MS

Blood Typing

ABO can exclude but not ID

DNA

Nuclear
Mitochondrial
Familial—Grim Sleeper case
Phenotypic Analysis

Electronics

Cell phones, computers, emails, texts, VMs

Criminal Mischief: Episode #03: Time of Death

Criminal Mischief: Episode #03: Time of Death Notes

LISTEN TO THE PODCAST: https://soundcloud.com/authorsontheair/03-timeofdeath

The ME’s 3 most important determinations: Cause, Manner, and Time of Death

Part II: Time of Death Notes

DETERMINATION OF THE TIME OF DEATH 

Determining TOD is critical
Both an art and a science
The sooner after death the more accurate the estimate
Changes death variable and unpredictable. 

Physiologic TOD, Estimated TOD, Legal TOD

Always a best guess
None of the methods are very accurate

Body temperature
Rigor mortis
Livor mortis (lividity)
Degree of putrefaction
Stomach contents
Insect activity
Scene markers 

BODY TEMPERATURE 

Normal body temperature is 98.6F
Body loses or gains heat until it equilibrates with that of the surrounding medium.
The formula is: Hours since death = 98.6 – corpse core temperature / 1.5
Cold/wind/water increase heat loss
Obesity, heavy clothing, warm still air, exposure to direct sunlight, and an enclosed environment slow heat loss. 

RIGOR MORTIS 

Spasm due to chemical reactions within the muscle cells after death.
Loss of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) causes the muscles to contract and stiffen.
Later loss of rigidity from the putrefaction process.
Rigor begins throughout the body at the same time
Appears first in smaller muscles- face, neck, and hands
Relaxes in same pattern
General rule for rigor mortis is 12-12-12
Changes due to: activity, body temp, ambient temp,
Cadaveric spasm 

LIVOR MORTIS (Lividity)

Purplish—exceptions for CO (carboxyhemoglobin), Cyanide (cyanohemoglobin), Freezing
Dependent areas—lying, sitting, hanging
Pale support areas
Gravity, then leaking into tissues
Shifting vs Fixed—Onset 1/2 to 2 hours/fixed by 8 hours
Mismatch of pattern and body position

THE RATE OF BODY DECAY 

Time Since Death
Putrefaction—ambient temp/humidity
Internal bacteria—sepsis hastens
Water X2/BurialX4
Ultimately skeletonize
Floaters
Mummification
Adipocere-from chemical process called saponification-reaction between certain bacteria and the body’s adipose (fatty) tissues.

Stomach Contents:

Stomach empties in 2-3 hours—protein, fatty meals
Intestine transient @ 24 hours

Insect Activity

Forensic entomologist

Insects help in two basic ways: Predictable developmental stages (blowfly); succession of insect species
Changed by body location, weather, season, night

Scene Markers

Includes information at the scene or from witnesses or family and friends.
Missed appointments, uncollected mail or newspapers, and dated sales receipts
Victim’s clothing—dressed for work, or morning jog

Criminal Mischief #02: Cause and Manner of Death Notes

Criminal Mischief #02: The ME’s 3 most important determinations: Cause, Manner, and Time of Death

Part I: Cause and Manner of Death Notes

CAUSE/MECHANISM OF DEATH:

Cause of death is why the individual died
Heart attack, GSW, traumatic brain injury, diseases

Mechanism-physiological derangement that causes death

One cause—several mechanisms

Example: MI-arrhythmia, cardiogenic shock, rupture 

Example: GSW—heart or brain damage, exsanguination. wound infection

One mechanism—several causes

Example: Exsanguination—GSW, ulcer, meds, disease 

Just as a cause of death can lead to many different mechanisms of death, any cause of death can have several different manners of death. A gunshot wound to the head can’t be a natural death, but it could be deemed homicidal, suicidal, or accidental.

MANNERS OF DEATH: For what purpose and by whose hand

NATURAL: Natural deaths are due to the workings of Mother Nature in that the death results from a natural disease process. Heart attacks, cancers, pneumonia, and strokes are common natural causes of death. This is by far the largest category of death that the ME sees. 

ACCIDENTAL: Accidental deaths result from an unplanned and unforeseeable sequence of events. Falls, automobile accidents, and in-home electrocutions are examples of accidental deaths. 

SUICIDAL: Suicides are deaths that come by the person’s own hand. Intentional self-inflicted gunshots, drug overdoses, or self-hangings are suicidal deaths. 

HOMICIDAL: Homicides are deaths that occur by the hand of another. Note that a homicide is not necessarily a murder. Homicide is a determination of the ME; murder is a legal charge that is determined by the courts. Though each would be ruled a homicide by the ME, the legal jeopardy is much different for a court verdict of negligent homicide as opposed to first- or second-degree murder. 

UNDETERMINED OR UNCLASSIFIED: This extra category is used in situations where the coroner can’t accurately determine the appropriate category. 

Examples:
Car/pedestrian
Heroin/Drug OD
GSW

Psychological Autopsy

Manner determines whether there is an investigation

Manner not fixed—can change
Proximate cause— the cascade of events
