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.

When examining a fingerprint, do you lift the print first then swab for DNA?

Asked by Renee over 11 years ago

That's always a good question. Black powder or superglue will not ruin the DNA, so we can photograph the print and then swab for DNA. Usually we're swabbing areas that we wouldn't normally be able to get a print from (like textured steering wheels or rough gun grips or the edge of a plastic bottle that someone drank from) so we do one or the other.

how can you identify from a random dna sample that the sample belongs to a human being, not an animal? lets say that you find a DNA sample and now you have to identify that this dna sample is of a human or an animal or cannot be classified at all

Asked by Rabi over 11 years ago

I actually don't know how a DNA analyst tells human from animal DNA, but I don't think it's very difficult. We have an easy field test called Hexagon OBTI that can tell animal from human blood in a matter of minutes.

Say that there was a crime scene with trama to the head and bleeding from the head and specialist forgot to take the temperature of that body, what is another way to determine the time of death?

Asked by bryce over 11 years ago

Time of death is not determined as precisely as it is on television, I know, and they often use a number of factors to make an estimate such as when the person was seen last, mail piling up at the door, rigor mortis, lividity, etc. But honestly a pathologist could answer that question much more accurately than I could. They are the ones that determine TOD.

I have read information regarding chemical enhancement techniques to view fingerprints in blood, however this got me thinking, does the use of fingerprint enhacement techniques such as powders suspension harm the confirmatory test for blood

Asked by Emily over 11 years ago

No. Almost all blood enhancement reagents will not destroy the blood for DNA testing. I don't think it would affect confirmatory tests either, but If we wanted to do a confirmatory test for blood such as phenolphthalein we would probably just do it on a spot where the marks were smeared or otherwise not useful as fingerprints.

Was just wondering what it took to become a forensic scientist, what did you have to take in college, what major?

Asked by Taylor M. almost 11 years ago

It all depends on where you want to work and what they require. At the coroner's office we all had at least a bachelor's degree in a natural science like biology, because there were not any forensic degrees then. If you want to be a DNA analyst you will probably need to major in genetics or biochemistry. At the police department where I work, with our very small lab, we are only required to have a high school diploma--but you get extra points in the interview process for advanced degrees so we all have at least a bachelor's.Hope that helps.

Hey, I'm very interested in becoming a forensic scientist myself. May I ask, what kind education is necessary to become a forensic scientist. Also where did you apply for your job? Did you go through private training after you were hired?

Asked by Zachary Assante about 10 years ago

If you look through previous answers you'll find a number pertaining to this. Each agency and position may have different requirements so the only way to know is to call the places you are interested in working at and ask them. For my current job I only need a high school diploma but we all have at least a Bachelor's degree. If you want to do DNA analysis they may require a PhD. I applied to the police department that posted the vacancy. Most have online postings now so it's pretty easy. Yes, I've had a lot of continuing education through other police departments and forensic organizations.

Is there anything wrong with having glasses or contact lenses if you want to be a forensic scientist? Will it interfere with your chances at being hired?

Asked by Barry89 over 10 years ago

No. I've worn glasses since the 5th grade and had no trouble being hired.
