Forensic Fridays: All About Autopsies

Most living people never visit the morgue.

Most never speak of the morgue, except during shows like CSI, Bones, or Hawaii 5-0. The popularity of forensic TV series, however, is social proof that there’s hidden interest in finding out just what goes on behind the autopsy suite’s closed door.
The word autopsymeans ‘to examine for yourself’. It’s a medical procedure that sounds simple in principle – taking a look at the outside and inside of a cadaver to establish cause of death. In practice, a post mortem (PM) examination can be highly complicated and time consuming; employing leading-edge scientific expertise.

There are three types of PM’s. A hospital autopsy is a non-legal process where the cause of death is known, but the caring physician wants to confirm a specific issue – such as a cancer tumor. A routine autopsy is conducted when the cause of death is not known, but foul play is not suspected. Then there’s a forensic autopsy – the one that’s going to be torn apart in a murder trial.

All autopsies follow a standard protocol. It’s the nature of the investigation that determines just how in-depth the procedure gets. The deceased arrives at the morgue and is catalogued with personal details and a registration number. Yes, they really do use toe-tags. The body is then placed in a refrigeration unit and waits its turn for examination. In a busy morgue this can take several days.
Usually two people conduct the autopsy. The pathologist, or medical doctor who is trained in the study of death and disease, is assisted by the deiner (German word for helper). Often there’s observers present; police officers, students, or technicians who come and go. The length of time varies – fifteen minutes to confirm a tumor, two hours routinely, and up to eight for a complicated forensic ordeal.
External observation can take a good portion. The body is removed from its shipping shroud, stripped, photographed, X-Rayed, weighed, measured, and identifiers such as race, age, hair and eye color, markings, abnormalities, as well as evidence of trauma or medical intervention is recorded. In homicide cases, the bulk of the evidence can be recovered in the external exam – clothing perforations, gunshot residue, lacerations, abrasions, hair, fiber, DNA, chemical contamination, or foreign objects. The observations are recorded on notes, diagrams, photos, and verbal dictations.
The corpse is placed supine, on its back, on the examining table which is an angled stainless steel tray draining fluids to a disposal sink. A plastic block is placed under the back to elevate the chest and recline the head and arms, making internal operations practical. A Y-incision is sliced from the tip of each shoulder, horizontally to the center of the chest, then vertically down to the pubic area. The skin is scalpeled back in a butterfly pattern accessing the thorax and abdomen, then the ribcage is removed exposing the upper and lower organs.
The major ones are removed, weighed, and cross-sectioned – lungs, heart, liver, kidneys, spleen, stomach, and intestines. Tissue sections are exscinded and fluids are extracted – blood, urine, vitreous humor, and digestive contents. These can be of immediate visual interest, or may tell later tales in toxicology and microscopic processing.
Cranial examination is the part that most newbies find difficult. The neck is now propped to elevate the head and the scalp is cut from ear to ear, peeled over the face and down the neck, then the skull cap is severed with a vibrating saw. The brain extracts easily and is often preserved in formalin to gel for later sectioning.
Completion involves returning the organs to the central cavity and sewing the incisions before releasing the body to a funeral home. Tissue and liquids are retained for histology and toxicology. In forensic cases, exhibits such as bullets, trace evidence, DNA standards, and clothing are transferred to the crime lab.
Often the cause of death is conclusive at autopsy. Occasionally nothing is known until the lab results come in. And sometimes… it’s never determined just why the subject died.
Our scientific understanding of life and death is extensive, but it’s far from perfect.

Do Do I Need a Coroner, Medical Examiner or Pathologist?


I’m so excited to have Garry Rodgers join my honored team of medical experts. To be honest, I’ve been looking for someone on the “other side of life” to offer their insights because I do see a fair number of forensic questions and this is not my area of expertise. I try to keep the living from crossing over.

Garry will be here on a regular basis doing Forensic Fridays and I’m so glad to have him. I hope you’ll check out his novel, No Witnesses to Nothing.

Welcome, Garry!

Hi. I’m Garry Rodgers and I’m delighted to be a guest on Redwood’s Medical Edge.

For over three decades I’ve been involved in the death business. I’ve been a Royal Canadian Mounted Police homicide detective, served as a sniper on Emergency Response Teams, and finished up my forensic career as a Coroner. So I’ve seen my fair share of bodies.

Everyone knows what a homicide cop does, and most would rather not be in the sights of a sniper, but there’s a lot of misunderstanding about the role of a Coroner as opposed to a Medical Examiner (ME) and to a pathologist. A bit of a history here.

All civilized jurisdictions have a judge of the dead whose duty is to find fact. Not fault. The facts to be determined are the Who, When, Where, How, and By What Means that the deceased expired. Once these facts are determined, the death must be classified into one of five categories; Natural, Accidental, Suicide, Homicide, or Undetermined. This method of fact-finding and classification is universal, whereas the structure of appointing the judge is not.

The office of the coroner dates back to 10th century England when the Crowner of the King (hence the word coroner) investigated any number of matters, including sudden and unexplained human deaths. This evolved into an inquisitional role where the coroner would conduct simple inquiries, or in cases of public interest, would hold inquests and compel witnesses to testify. Coroner appointments generally went to upstanding citizens of the community, not necessarily to those of a medical, legal, or investigative background.

As science progressed, it became prudent to retain the expertise of medical professionals, particularly in the clinical areas of autopsy and toxicology. This coincided with the massing of population in urban areas. Out of practicality and economics, the cities would employ full time medical doctors as examiners who’d delegate field investigations to lesser qualified persons. The rural areas, having a lower caseload, adopted the reverse where they’d contract out the specialties.

A pathologist, on the other hand, is a medical examiner who’s been specifically trained in the study of death and disease. The term pathologist dates back to ancient Greece; pathos meaning suffering, and logos meaning writing. Taking it a step further, a forensic pathologist signifies a specially-trained medical doctor who’s qualified to testify in court.

I can’t say the Coroner system is any better or worse than the Medical Examiner system. The professionals may have inverse roles, but all are exceptionally well trained. Both speak to the deceased’s interests and that’s what’s important. Death investigations have become more complex as science advances and, regardless of the administrative issues, having the right people doing the right jobs is key to determining the proper cause and classification of death.

Just a note on the personal qualities required to investigate deaths. First you need an inquisitive mind. Often things aren’t what they seem on the surface, and it’s through attention to detail that the facts rise. Second – empathy. You deal with those in the world which the deceased suddenly left; families, friends, co-workers, and to them it’s not just another case. Last, you need a strong constitution. Some of the death scenes can be exceptionally unpleasant.

In an upcoming sequence of posts, I’ll take you deeper into the world of a coroner. We’ll follow a true case which I investigated that employed the spectrum of forensic techniques. I was able to correctly classify the death, but I’ll assure you… it wasn’t what it seemed on the surface.
So stick around. I promise to be interesting!

Author Question: Post-Mortem Injuries

Giacomo asks: I’m writing a scene where the killer cuts off the victims’ lips while they are alive. how would the M.E. know if the vic was alive or not by looking at the corpse?
Jordyn says:
Sometimes, the best thing for me to do is offer an author several resources to delve through to find the answer they’re looking for. Here’s the list of resources I sent to Giacomo:
1. What Crime Scene Insects Reveal About the Victim’s Wounds: http://insects.about.com/od/forensicentomology/p/csiwounds.htm
2. Antemortem vs. Postmortem Injuries. Which means injuries before and after death.  http://shs.westport.k12.ct.us/forensics/07-injuries/antemortem_&_postmortem_injuries.htm
3. Twenty-seven differences between antemortem and postmortem wounds: http://ourforensicmedicine.blogspot.com/2010/02/27-differences-between-antemortem-and.html
4. Medico-legal significance of a bruise: http://www.legalserviceindia.com/medicolegal/bruise.htm

Does anyone else have any resources that might help with Giacomo’s question?***********************************************************************Giacomo grew up in a large Italian family in the Northeast. No one had money, so for entertainment he and his family played board games and told stories. He loved the city—the noise, the people—but it was the storytelling most of all that stuck with him. Now Giacomo and his wife live in Texas, where they run an animal sanctuary with 41 loving “friends.” Sometimes he misses the early days, but not much. Now he enjoys the solitude and the noise of the animals.

 

Medical Question: The Morgue

DV asks: I am writing a thriller right now and need a description of a large city hospital morgue. I haven’t tried to secure a tour yet (do they even allow that?) at a city nearby. All I need is to know how they’re set up. I’ve read they’re usually in the basement near a loading dock, and they’re usually unmarked and secure.
Do they use a wall of refrigerated drawers? If not, what does the room look like? How are the bodies marked? Do they still use toe tags or is it all done electronically? Do they include cause of death? I’m afraid the smaller town I live in wouldn’t have the same kind of morgue as a large city (the book takes place in LA). I’d like to have at least a semblance of reality.
Jordyn says:  DV, thanks for sending me your question.
I’m not familiar with a large city morgue either. Just a hospital morgue. I think you could probably call and set-up a tour. I’m sure you won’t be the first person to ask. Another thing I would recommend would be to take your local police department’s citizens’ police academy. I took one locally last year and it was a wealth of information. Sometimes, through a venue like this, you might get the chance to tour a morgue.
Considering your question as a medical person, this is how I would research it.
Do a Google search for known medical examiner’s buildings and get photos of the structure via the Internet for the outside look.
Next, go to You Tube and search for “morgue tour”.
I thought this one was actually pretty good and gave decent enough info to set up a scene.

You could view others as your heart desires. Any other suggestions for DV?

Medical Question: 1950’s Coroner

April asks: For a grad assignment, I have to come up with murder mystery plot line.  I have the general plot line down, but I’m wondering how efficient an autopsy in the 1950s would be?
I need the victim to be poisoned, most likely by a relatively common plant–probably a daffodil, yew, or Wild Cherries (those are my top three choices at the moment).  However, I have no idea how much or what kind of poisons would have been detectable by a small-town, 1950’s coroner.
Jordyn says:  First thing, is a medical examiner and coroner are very different. A medical examiner is a trained physician (the one who does the autopsy) and the coroner is an elected official to decide how an investigation should proceed. For instance, if the coroner feels the cause of death does not involve a crime, there may not even be an autopsy.

The second thing you need to determine is when tests for toxicology/poisons came about: “Screening tests, such as radio immunoassay, enzyme immunoassay and thin-layer chromatography are often very sensitive, but not very specific. Because they are very sensitive, they will very likely detect the chemical/poison if it is, indeed, present in the sample. Unfortunately, because they lack specificity, they are given to false-positives – mistaking a substance with a similar chemical make-up for the suspected poison. Unless the results of these screening tests are confirmed with a reliable testing methodology, such as gas-chromatography/mass-spectrometry, the results of these screening tests do not satisfy the evidentiary standards for admissibility.”

When I did a little searching, some of these tests were not developed until the 1950’s and 1960’s. So, for them to be widely used would take some years. If you want to be very specific in your ms, you need to research when each of these tests were developed for forensic use. For example, google “development of forensic radio immnoassay”. That will give you a timeline for when they may have been able to detect your chosen poisons on autopsy. I did link you to some forensic timelines below— there are a few of these tests mentioned.
I think the easiest route for you would be this: This small town has a coroner who doesn’t suspect anything criminal is going on. This is still very common today because a coroner may have absolutely little or no medical training and probably no forensic training. Then, maybe based on the victim’s symptoms before death, the very smart local doctor begins to think someone is poisoning these people. This sets up conflict which is always a must. I would research the symptoms people have when they ingest the items you have listed. Then, maybe this local doctor can push the coroner into having a fancy, big-town ME do an autopsy.
