Forensic Scientist

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 ever gotten emotionally attached to a case?

Asked by Jordan Hall over 10 years ago

No. There are cases and victims that I feel sorrier for than others, but nothing reaching the level that I would call emotionally involved. Everything is over by the time I get there, and then I don't usually see the victims or other parties again so there isn't an opportunity to bond.

Girl claims rape, boy says didn't happen. DNA came back inconclusive from rape kit except something in girls underwear they say is boys. How is that possible when nothing was discovered on girls body of boys, anywhere?

Asked by Momma over 10 years ago

Because human bodies are in constant flux. Cells slough off, fluids wash out other fluids, but a stain on a piece of cloth doesn't change.

How long can GSR last on clothing or on a person?

Asked by Jailah over 11 years ago

On the shooter's hands, not very long. When we did GSR testing we would not do it if more than 4 hours had elapsed since the shooting. On clothing, it could depend on the type of material and how far away the item was--if it's a smooth fabric it would probably brush right off, but a more fuzzy type of thick material might get some particles stuck in it.

That was talking about primer residue. Gunpowder residue is bigger, heavier, and hot so it can fuse to some fibers or get 'stuck' to the item by the victim's blood.

Hi Ms. Lisa. My name is Candace and I really want to become a forensic scientist. How long does it take and is it worth it? I've spent all my life in a morgue. I love it all and does it pays well?

Asked by Candace Mckenzie over 10 years ago

let me try to answer these one by one:You will need at least a 4 year degree, most likely. It's well worth it if you really enjoy the work. Nothing in the public sector pays as well as the private sector.If you've spent all your life in a morgue, you probably already know a few forensic scientists. The best thing to do is talk to them and see what the requirements are in the places you want to work.

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 about 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.
