Forensic Scientist

Forensic Scientist

LIsa Black

Cape Coral, FL

Female, 49

I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.

Have you become desensitized to death and violence? Are there still some crime scenes you see that make you sick because of how gory or depraved they are?

Asked by mbyrnes over 4 years ago

I don't consider myself desensitized. I still say "Oh, that's terrible," when I read about someone's death in the paper. I just don't get sick at the sight of bodily fluids. It seems like you either get used to that instantly, or you get into another line of work. It's not exactly the same thing as having a weak stomach--I've known guys who were homicide detectives for 20 years and still had a weak stomach. But when I'm standing at a crime scene there are so many things to think of (plus the overriding "Don't screw up!") that I don't have time to think about how awful this is. To me it would be more nervewracking to be an ER nurse and have someone's life depending on my instant decisions; at a crime scene, the crime has already been committed, so I couldn't have prevented it and I can't do anything about the fact that it happened. I think also that, without putting it into words, I tell myself that the person died right away. I get more upset at seeing the things the hospital did, the tubes, the halo brace, because I know the person must still have been alive for that to be done. Basically, if this work is going to upset you, do something else. It doesn't help anyone to be traumatized by your daily job.

What degree and certification would I need become a forensic scientist? I'm currently majoring in criminology, but would switch if something else was better.

Asked by Alejada over 4 years ago

Again, titles and job requirements aren't uniform, so the only way to know is to call the crime labs in your area or whereever you might be interested in working and ask them. At the coroner's office we had to have at least a bachelor's in a natural science (this was before they had forensic science majors). At the police department where I am now, they only require a high school diploma but you get more points in the interviewing process for having a four year degree, so we all have one. You can also go on the websites for professional organizations such as the American Academy of Forensic Sciences and check out their job vacancy postings and see what the various positions require. Good luck.

What type of classes did you need to take to become a Forensic scientist?

Asked by Nikkie about 4 years ago

If you see the two Q&As above, you can't go wrong with science classes. When I was in college they didn't have courses specifically in forensic science, so that wasn't an option. And different agencies will have different requirements, so you might want to go online and check out the different vacancies to get some idea of what requirements are out there.

what would change a corpse hair from highlighted blonde to an orange red in an african american?

Asked by shunlegg about 4 years ago

I don't know, unless the corpse lay in bleach or some other chemical that would react with the bleach in the hair. Dark hair can (I know from personal experience) turn kind of orangy when you try to lighten it. Otherwise hair does not change much either while living or dead.

I'm currently in the Navy and looking into taking college courses towards forensics but I do have a charge of accessory after the fact to a felony in 2002. (Closed file) Would this hinder my ability to obtain a career in this field? If so how badly?

Asked by jwalk over 4 years ago

I honestly have no idea, and suspect it would depend on where you are applying--whatever the hiring agency's policies are. I'll ask my boss and get back to you.

 

OKAY! I finally asked my supervisor about this, and unfortunately the news is not too encouraging. If you were found guilty of a felony, you might have a real problem getting a job with a law enforcement agency. But just because the crime was a felony doesn't necessarily mean that was your charge, you could been found guilty of first degree misdemeanor or some lesser charge, and that might not preclude you from employment. Also, smaller agencies might be willing to waive this exclusion especially with military experience. And this is only in the event that you were convicted. If you were simply charged with the crime but not convicted, then most likely it isn't a problem at all. The only way to know for sure is to ask a few of the places you'd be interested in working at and see what they say.

Have you ever worked on a scene that you'd describe as the "perfect crime" in that the perp literally left NO trace of his presence?

Asked by Seth over 4 years ago

It depends on how you define 'perfect'...if I can't tell the perpetrator has even been there then we wouldn't even know a crime has occurred, so I wouldn't know it was a perfect crime. If you mean 'perfect' in that the guy didn't leave any DNA or fingerprints that we found, sure, all the time. I've had plenty of burglaries in which it was apparent that a burglary occurred, but between humidity and surface conditions and what the perp had to touch in order to get the job done, I find no fingerprints at all (not even the people who live there). If you walk up and shoot someone (especially with a revolver, so no dropped casings) and walk away, you're not going to leave anything. Maybe a hair or a skin cell, but how would a CSI find that on a dirty street? Hence, a 'perfect' crime. Unless you get a parking ticket on the next block or a witness waiting for a pizza delivery happens to look out their window or there's an ATM camera you didn't know about.

And something else I always wondered. Just HOW MUCH of a fingerprint is unique to every human? If someone leaves only a partial print, e.g. a 1/4 of a thumbprint, is THAT unique to him and only him?

Asked by Sascha over 4 years ago

Every part of a fingerprint is unique to the person. Whether the latent print has sufficient information to identify it to a person depends on its clarity and volume and the experience of the examiner. There's usually more activity around the center of the finger pad than at the edges or the tip, for example. But exactly how much of what type of information an examiner needs to make an identification--unfortunately there's no simple answer for that. Fingerprints aren't like DNA, there's no handy table of X allele plus Y allele times population data, so there's no neat way to quantify it. On this topic, my pet peeve: When characters on TV say "It's just a partial." Unless your perpetrator stood at the crime scene and rolled his fingertip over something, from one edge of the nail to the other, then EVERY latent print is a partial!
