Writers need to know that procedures vary across the country. California, for example, is practically a world of its own and definitely beats a different drum than the rest of the country. I know because we lived there for well over a decade. I’m also quite familiar with how things go in other parts of the country, such as Virginia and North Carolina, Ohio, Wisconsin, and more.

No two states are identical—laws, rules, and regulations vary from place to place. In fact, procedures, guidelines, governance, and even local ordinances differ. No two law enforcement agencies operate in precisely the same manner. Their differences may be slight, to great.

The takeaway is this—if your story is set in an actual town, city, or county, please research those specific areas, especially if your goal is realism.

No, Medical Examiners Don’t Always Show Up at Murder Scenes

In some locations, typically rural, medical examiners may not respond to homicide scenes, or suspected homicide scenes. Instead, as is the case of many areas within in the Commonwealth of Virginia, EMS or a funeral home is responsible for transporting the body to a local hospital where a doctor or local M.E. examines the victim. I’ve investigated numerous homicides where the medical examiner opted to not respond to the scene of the crime.

If a suspicious death occurs during the nighttime hours, the exam may not occur until the next day when the M.E. returns to work after a good night’s sleep. And, in those rural locations, if an autopsy is to be performed it is not the local medical examiner who’d conduct it. Instead, the body is transported to a state morgue which could be located hours away.

In Virginia, there are only four state morgue locations/district offices (Manassas, Norfolk, Richmond, and Roanoke) where autopsies are conducted. Each of the district offices is staffed by forensic pathologists, investigators, and various morgue personnel.

Breaking Bread with Kay Scarpetta

The Office of the Chief Medical Examiner (OCME) is located in Richmond (the office where Patricia Cornwell’s fictional M.E., Kay Scarpetta, worked). This is also the M.E.’s office responsible for conducting the autopsies on the homicide cases I investigated. The real-life Kay Scarpetta was our M.E., and she is brilliant.

She, in fact, and one of her assistants, joined Denene and me at dinner at the Commonwealth Club in Richmond the night Denene received her PhD in pathology from Virginia Commonwealth University. Ironically, it was this very assistant to the real-life Kay Scarpetta who months later performed the autopsy on a bank robber who engaged me in a shootout. And it was she who, in explicit detail, informed me that four of the five rounds I’d fired into the center of the robber’s chest were fatal rounds. The fifth, she told me, entered the skull at an angle that would not have resulted in death.

There are several local M.E.’s in Virginia (somewhere around 160, or so) but they do not conduct autopsies. Their job is to assist the state M.E. by conducting field investigations, if they see fit to do so, but many do not. Mostly, they have a look at the bodies brought to  hospitals by EMS, sign death certificates, and determine whether or not the case should be referred to the state M.E.’s office for autopsy. They definitely do not go to all death scenes. Again, some do, but not all.

An example (one of many) was a drug-related execution in a county near where I worked as a city police detective. The sheriff of the county contacted my chief and requested that I assist in the investigation. Following the evidence, I and the sheriff’s investigators located the killers and after interrogating one of the suspects, he led me to the crime scene where we found the deceased victim. The suspects shot and killed the victim and then carried and dragged the body several yards, deep into a wooded area.

The men, after tiring of dragging the dead weight, left the body between a few small trees, in a thicket of briars and poison oak. Insects—beetles, flies, etc.—had begun their feasts. Scores of ants marched in lines across the body and in and out of the mouth, nose, and ears. A wasp crawled from inside the mouth and stood at the tip of the man’s tongue while stretching its wings. Hundreds of mosquitos swarmed around us and punctured our exposed flesh at will. They were relentless, and each of us had to return to our various cars to retrieve whatever protective clothing we could find.

The local medical examiner was spared of the mosquito bites and poison oak allergies because he chose to not respond to the scene. Instead, he settled for our statements, photos, and my video recording. He requested that the body be delivered to a local hospital. EMS placed the remains into a body body bag, sealed it, and then headed off to the morgue with a deputy sheriff tagging along for the ride to ensure the chain of custody was not broken.

Me standing on the left at a murder scene where a drug dealer was executed by rival gang members who then hid the body in a wooded area. I was asked to assist a sheriff’s office with the investigation. The medical examiner was called but elected to not go to the scene. The body and sheet used by the suspects to drag the victim were placed into a body bag and then transported to the morgue via EMS ambulance.

Pursuant to § 32.1-283 of the Code of Virginia, all of the following deaths are investigated by the OCME:

  • any death from trauma, injury, violence, or poisoning attributable to accident, suicide or homicide;
  • sudden deaths to persons in apparent good health or deaths unattended by a physician;
  • deaths of persons in jail, prison, or another correctional institution, or in police custody (this includes deaths from legal intervention);
  • deaths of persons receiving services in a state hospital or training center operated by the Department of Behavioral Health and Developmental Services;
  • the sudden death of any infant; and
  • any other suspicious, unusual, or unnatural death.

* Remember, “investigated” does not mean they have to go to the actual crime scene.

Again, me on the left as a sheriff’s office crime scene investigator points out the location of spent bullet casings, drag marks, and a blood trail. Pictured in the center are a county sheriff and prosecutor. The M.E. elected to not travel to the scene. As good luck would have it, we had the killers in custody at the conclusion of a nonstop, no sleep, 36-hour investigation.

After a lengthy interrogation, two of the four confessed to the murder. Of course, they each pointed to someone else as the shooter, and he, the actual shooter, placed the blame on his partners. But all four admitted to being present when the murder occurred and all four served time for the killing.

In the areas far outside the immediate area of Virginia’s four district offices of the chief medical examiner, where officials rely on local, part-time medical examiners, it is typically police detectives/officers who determine when a body can be removed from the scene. EMS, after checking for signs of life, stand by until the police instruct them to transport the body.

If the local M.E. shows up, and they’re almost always called, he/she will have a say in when the body is to be removed, but it’s rare that they do anything other than gather information for their notes and discuss possibilities and evidence with the police investigators.

Take Two Bodies and Call Me in the Morning!

In many cases, the local M.E.’s will simply instruct the calling detective to have EMS transport the body to the hospital morgue where they’ll take a look when they have a chance. They’ll sometimes ask to speak to the EMS person in charge of their crew to verify that the victim is indeed, well, dead.

The pay for local M.E’s in Virginia is a “whopping” $150 per case. Local M.E.s receive an extra $50 if they actually go to a crime scene. Again, many do not. Interestingly, funeral homes pay the local medical examiner $50 for each cremation he or she certifies.

Local medical examiners in Virginia also provide cremation authorizations for funeral homes and crematories. Cremation authorizations are required for cremation of anyone who died in Virginia. Funeral homes performing cremations must pay the local medical examiner $50 for each authorization.

The requirements to become a local M.E. in Virginia are:

  • A valid Virginia license as a doctor of medicine or osteopathy, Nurse Practitioner, or Physician Assistant
  • An appointment by Virginia’s chief medical examiner
  • A valid United States driver’s license

Once someone is appointed as a local medical examiner their term is for three years, beginning on October 1 of the year of appointment.

The four district offices employ full-time forensic pathologists who conduct all autopsies. Obviously, a physician’s assistant is not qualified to conduct an autopsy, nor are they trained as police/homicide investigators.

Remember, things are never the same/uniform across the country. It’s always best, if you’re going for 100% realism, to check with someone in the area where your story is set. The rules and regulations on one side of the country may not be the same on the other. And the middle of the country may also be totally different from the other localities.

For example, in one Ohio county, a coroner there mandated that autopsies be performed for all deaths that occurred during vehicle crashes. This is not so in other areas of the country, or even in other locations in Ohio. By the way, at the time, the Ohio coroner’s office received $1,500 per autopsy performed, with $750 of the sum going to the pathologist performing the exam.

There’s nothing in this world that can be compared to entering an abandoned house in mid July, in the south, to begin working a murder case. If the stifling heat, humidity, and smell of decomposing human flesh and organs don’t get to you, well, the flies, maggots, and other creepy crawlers certainly will. Without a doubt, it’s a full-on attack of the senses. But, it’s a job that falls into the laps of homicide cops—it’s what they do—and it’s a job that requires a special skill set. Not to mention a stomach made of cast iron and steel plating.

But, once you’re past the stench, gore, fly-swatting, and overall feel of ickiness, solving murder cases are a bit like writing crime novels … sort of.

Writers typically begin their stories knowing the identities of the murderers du jour, right? Protagonists typically work toward a “killer” ending to the story in which they travel, while their creators provide clues along the way that help their fictional heroes and readers solve the carefully plotted crimes.

Real-life detectives begin their journeys with an initial report that’s a written introduction to the basics—victim’s name, location where crimes took place, weather conditions, dates, times, responding officers’ names, time of arrival of the medical examiner, witness names and statements, if any, etc. This information, much like the very first Post-it note of a plotting author’s outline launches a story into a convoluted journey to the final page of a book, provides the starting points for investigations. And, those initial police reports often serve as guides that determine which direction the investigations should follow.

Remember, no two investigations are the same!

What follows the reading and studying of the initial police report or, an author’s first Post-it note, is an extremely detailed and meticulous prying, pawing, digging, and rummaging through each and every aspect of all the twists and turns and potential characters/suspects. No stone is left unturned, and no potential piece of evidence is left unexamined. For detectives, this often results in lots of long hours without sleep, meals, or time to rest. For writers, this means tons of sticky notes placed in all the right places, tons of research, police ride-alongs, and attending the fabulous Writers’ Police Academy.

When I approached a case where the suspect’s identity was unknown, and clues and information were scarce or non-existent—after collecting physical evidence—I often found it helpful to begin by first eliminating people who could NOT be involved, such as the people who had solid, unquestionable alibis. Then, I’d eliminate the folks whose innocence was proven by physical evidence (fingerprints and DNA didn’t match, etc.). It was often the last man or woman standing who committed the crime.

Writers, in lieu of using actual evidence to eliminate characters/suspects, they develop fictional evidence to do the same. And when something doesn’t seem quite right with a scene or character, well, the writers then simply removes a sticky note here and there and toss them aside. However, both detectives and writers typically file any discarded information in the event it’s needed at a later time. And, like writers, cops often find that information gained/gathered in one investigation just may be valuable in the next.

To Step Into a Murder Scene is Like …

So let’s open the door to the spooky house at the end of your street—the old Victorian that’s been empty for two years and is now surrounded by waist-high weeds. The once beautifully manicured lawn is now a graveyard for litter and other garbage left behind by transients and the kids who toss their empty fast food wrappers and plastic soda bottles over the rusted chain-link fence. Window panes are broken and many of shingles have fallen from the roof, leaving behind patches of tar paper and rusted nails.

For months now you’ve seen a homeless man going and coming, but this morning you realized that he hadn’t been around in the past two weeks. And there’s that strong odor. Like something is … dead.

So you call the police and the next thing you know your neighborhood is overrun by patrol cars and crime scene tape. You even heard one officer say something about murder.

Inside the “spooky” house, detectives are doing what they do best. They’re checking all the boxes on their mental checklist. And now their focus is on the victim.

The Effects of Death on the Human Body

Prior to the removal of a body from the crime scene, homicide investigators should note (and photograph) the presence of each of the following in his/her report:

1) Livor Mortis/Lividity (color, location, blanchability, Tardieu spots, other coloring). Are these consistent or inconsistent with the current positioning of the body?

Remember, lividity is the pooling of blood/purplish staining of tissue at the lowest portions of a dead body, caused by gravity. Livor continues to form for up to 8 – 12 hours after death. This process can be slowed to as much as 36 hours in a cool environment, including a morgue cooler.

To test for blanchability, a death investigator uses a finger(s) to push against the flesh. The pressure forces blood out of the capillaries in that area, causing the flesh to present as much lighter in color. If the pressure does indeed cause a change in skin color, the flesh is blanchable. This tells the investigator the body is still within the lividity period, meaning the victim died sometime within the past 12 hours, or up to 36 hours in cool surroundings.

You can try this on your own skin. Use a finger to apply pressure to the back of your hand. Release the pressure after a second or two and you’ll see the change in skin color (obviously you’ll use the finger of one hand to press against the skin on the back of your other hand). By the way, if you needed that instruction, well, the warning to remove Pop Tarts from their wrapper before heating are probably very important to you. And, if there was no change in your skin color, well, I hope your life insurance policy is up to date.

Tardieu spots are dark, circular areas—capillary ruptures.

2) Rigor Mortis

Muscles contain bundles of long, narrow cells. While we’re seated at our computers reading blogs and watching goofy videos, our muscles are, for the most part, at rest.

While resting, our muscles pump out calcium ions which build up electrical potential (energy). Then, when we’re ready to make that run to the mailbox to retrieve the latest royalty check, a nerve impulse causes those ions hook up with actin and myosin filaments and the muscles contract (become tighter). They remain in that state until adenosine triphosphate (ATP) binds to the myosin, and before you know it the muscles once again relax.

Got it now? No, well, don’t worry. All we need to know is that ATP has an obsession with oxygen. It absolutely has to have it to survive.

Actually, the body needs oxygen to produce ATP. Therefore, when a person stops breathing (no oxygen) the body ceases to make adenosine triphosphate. Without ATP our muscles can no longer relax. And when the muscles can’t relax, what happens? Right, the body stiffens, and that, my writer friends, is called Rigor Mortis.

3) Degree of decomposition (putrefaction, adipocere, mummification, skeletonization, etc.). Everything affects decomposition, from air temperature to animals and insects to shellfish, fish, alligators, snakes, and turtles, when the body is in water. Even soil types and clothing can affect the rate of decomposition. Interestingly, newborns who have not yet been fed, decompose slowly since the body is basically sterile. However, an injury or being fed will cause a newborn’s body to decompose more rapidly.

a) Putrefaction – the final stage of decomposition. Presents as discoloration of tissue, disfiguration, liquefaction of tissue, bloating due to gases forming in the tissue and organs.

The general order of putrefactive changes are as follows:

First to go are the larynx and trachea, followed by…

– stomach, spleen, and intestines

– lungs and liver

–  brain

– heart

– bladder, uterus, kidneys

– skin, tendons, and muscle

– bone

*The prostate resists putrefaction for a long time.

b) Adipocere – a waxy, soap-like substance that’s sometimes formed during decomposition. Normally caused by moist or damp conditions surrounding the decomposing body.

D. Insect and animal activity. Obviously, insects and animals can and do consume body parts. Animals may also scatter human remains, sometimes making the murder scene a bit more difficult to understand, at first look.

E. Scene temperature. Death investigators make note of the ambient temperature at the location of the body, and the method used to obtain it.

F. Description of body temperature. Is it warm to the touch? Is the flesh cold, or frozen.

It is extremely important to preserve the security of the body. Remember, the body is more than likely THE most important piece of evidence in a murder case. Investigators should oversee the labeling, packaging, and the removal of the remains by the M.E’s personnel, or EMS, etc. An identification tag should be attached to the body to prevent any mix ups later, at the morgue (yes, this has happened, and on more than one occasion).

Finally … No, police detectives do NOT use thermometers of any type, including rectal thermometers, to check the temperature of a dead body. It is not in their job description to do so. Yes, I once read the rectal thermometer thing in a book. So, no, no, and NO!

By the way, the image at the left is of a grilled pork chop. Had your stomach turning for a moment, huh?


*Remember, laws and procedure differ across the country. What happens in San Francisco or L.A. may be, and likely are, entirely different in Richmond or Baltimore or Dallas or Phoenix or Denver or Kansas or ….

*The black and white images contained in this post are from an actual crime scene, the largest mass family murder to occur in the U.S. It’s a case I featured in my true crime tale, Murder on Minor Avenue.

As part of my research prior to writing the story I visited the scene(s), interviewed dozens of people involved in two cases, including police detectives, neighbors, prosecutors, judges, family members, etc., and I visited the gravesites of the slain. Murder on Minor Avenue was published in an anthology called Masters of True Crime: Chilling Stories of Murder and the Macabre (edited by R. Barri Flowers) Publisher – Prometheus Books.

 

You’re in the prime of your life and you love to throw those crazy parties, the kind guests rave about for months afterward. They love that your backyard is a giant Slip-n-Slide hosed down by a fountain of beer. That you hire the best DJs with stage names like “DJ Hot Wing” and “DJ Jak Reach Her” shows your coolness level is off the charts. Alcohol flows from the taps in your kitchen and bath. Speakers the size of minivans pump out the jams at levels that drown out the sounds of the police helicopters hovering overhead. Neighbors have 911 on supersonic speed dial.

Yeah, those kinds of parties.

Your career as a top bestselling author is over the moon successful, the factor that funds your extravagent lifestyle. So successful, actually, that each of the 200 books you published last year are selling at the rate 450 per second. Lifetime and Netflix have purchased the rights to your entire backlist. Your latest book, Dark and Stormy Night, It Was, was just made into a blockbuster hit movie starring Jodie Foster and PeeWee Herman.

Reviewers say you’re destined to be remembered along with the greats of the thriller genre, such as Hitchcock and Edgar Allan Doe.

Edgar Allan Doe

Unfortunately, for you and your fans, four unwelcome party-crashers showed up at your latest shindig. Together, those four compadres who arrived one at a time—-the Mortis triplets and their cousin Demise—transformed your body into a cold and soulless and stiff chunk of instantly decomposing meat.

The process started back when you opted for a combination of liquor, cigarettes,and practically no sleep, over a healthy diet and exercise. You chose partying over the “right things” in life. Your excessive boozing and lack of responsibility, in fact, drove the family away from you and your circus-like lifestyle. And the moment they left, taking with them the last remaining bit of sanity in the household, was the point in time when the four party-crashers began eyeballing you as the perfect candidate for their plan. That was also the time when you started your dealings with the guy whose Uncle Vinnie operated a business out the a rear office in the Pleasure Palace strip club.

As your luck went, you’d decided to sleep with Vinnie’s wife and then Vinnie found out and he sent Demise to your party. Demise asked his cousins to tag along.

The Party-Crashers

Demise is the first of the crashers to the party. In fact, he always shows up before the others, but they’re never far behind.

Hi, my name is Demise

It’s Demise’s job to stop your heart and halt your breathing. He starts the changes to your body.

For example, the second Demise strikes, the skin begins to pale (pallor) and the muscles immediately begin to relax—all of them, which can produce some pretty unpleasant effects around the south end of the body, if you know what I mean. Then Demise steps aside to allow the Mortis triplets to do their thing.

The Mortis Triplets

The Mortis brothers, —Livor, Algor, and Rigor show up to the party separately, one at a time, and when they arrive … well, let’s just say the host is the center of their attention. And boy do they ever “spoil” him.

Algor mortis is simply the cooling down of the body after death. It’s the quest to reach room temperature.

One method of determining the time of death is to take the rectal temperature of the deceased. Next, subtract that number from 98.6 (average, normal human body temp), and then divide the remaining number by 1.5 (the average cooling rate of a body per hour under average conditions). The result is the approximate number of hours that passed after the victim kicked the bucket.

Livor Mortis, or lividity, is the pooling of blood in the lowest portions of the body. Lividity is caused by gravity and begins immediately after death. The telltale signs of livor mortis, the purplish discoloration of the skin, begins the moment the heart stops pumping. This process continues for approximately 6-12 hours, depending upon surrounding conditions, until it becomes fixed, permanently staining the tissue in the lowest parts of the body. When large areas become engorged with lividity, the capillaries in those areas sometimes rupture causing what’s known as Tardieu spots. Tardieu spots present as round, brownish blacks spots.

Rigor Mortis, the contracting and stiffening of the muscles after death, takes a couple of hours to begin and completes in approximately 8-12 hours. The process starts in the smaller muscles of the head and face and moves downward to the larger muscles. When rigor is complete, the process reverses itself starting with the lower large muscles and ending with the smaller face and head muscles. The entire process can last for approximately 48 hours. The body will quickly decompose after rigor is complete.

A person’s body goes stiff in the position they were in at the time of death.

Therefore, if a person died while lying on his back with one arm held straight up and the other straight out to the side, and the police discovered that same body in a bathtub, they’d probably conclude that someone moved the victim after death had occurred. After all, no one sits in a bathtub with their arms in those types of positions … do they? By the way, cops should not automatically rule out things simply because they’re different. Still, in the bathtub with one hand aimed skyward and the other pointing to a tube of Preparation H, a clump of tangled bobby pins, and a tin of ear wax remover. Yeah, somebody moved this one.

– Rigor mortis can cause contraction of the muscles in the epidermis, which also causes goose bumps to appear.

– Hair and fingernails do not continue to grow after someone dies. The skin around them begins to recede after death, which gives the appearance that they’re still growing.

– Age, illness, ambient temperature, fat distribution, and physical exertion just prior to death can all affect the rate of rigor mortis

When the triplets complete their tasks, well, the party’s over.

Sweet dreams …

While we’re alive our body temperatures are determined by metabolism. It’s a different ballgame, though, once the bucket is kicked.

After death, the body’s core temperature remains fairly constant for a couple of hours. Then it begins to cool by radiation, conduction, and convection, at a rate of 1.5 degrees per hour, until it reaches the ambient temperature—20-30 hours later.

However, investigators shouldn’t use the body temperature as the sole means of determining when a victim died. There are factors that could, and do, alter the natural cooling process.

When the “moment” arrives and the victim succumbs to wounds, illness, or natural death, there are elements that may affect the cooling rate of the body, such as:

  • Ventilation: A room that’s well-ventilated could actually speed up the rate of cooling by increasing the rate of evaporation.
  • Humidity: A body in a humid location cools at a slower rate than one in a hot, dry climate.
  • Insulation: A body that’s wrapped in something (including excess body fat) cools slower than one that’s left out in the open.
  • Surface temperature: A body lying on a hot surface will cool at a slower rate than one that’s found lying on a cold surface.

And, of course, a body in a hot environment cools much slower than one found lying in a in the snow, or a vat of ice cubes.

There are also factors that come into play that could alter the body temps even before death occurs, such as:

  • Consumption of drugs, extreme physical activity, and fever could all increase the body temperature.
  • Hypothermia could lower the body temperature.

These factors would change the length of time it takes a body to reach the surrounding air temperature.

10.4 Toe Tag

Finally, the rate of cooling also affects other “after death” processes, such as rigor mortis—heat speeds up rigor and cold slows it down.

By the way, other factors may also speed up rigor, such as extremely violent exertion prior to death, and alkaloid poisoning. Factors that could slow the rigor process are hemorrhaging by exsanguination, and arsenic poisoning, to name a couple.

And … a handy rule of thumb for decomposition:

One week in air = two weeks in water = eight weeks under ground.
