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.

Hey Lisa:) I was wondering if DNA found in saliva is still discoverble if A) it has been watered down, for example if someone was to spit in a glass of water, and if so how much water before the DNA is too hard to find?

Asked by sandaM over 9 years ago

It would still be discoverable up to a point. How much dilution it could take, I'm afraid I don't know.

Is their a way to determine which vehicle hit which from the damage say 2 vehicles are stopped on the highway one backs in to the other then insists the back car rammed him. Marks on the road are nonexistent because of a blizzard

Asked by Gabr over 9 years ago

Someone trained in accident reconstruction might be able to do so, but not having marks on the road makes it more difficult.

Do you ever get called to crime scenes to conduct your own investigation or is the evidence brought to you for analysis? Do most forensic scientists get to do both crime scene investigations and analysis? Thanks for your time.

Asked by Chicken about 9 years ago

I do both, but it depends entirely on your department. People at smaller departments usually have to cross train and fill several roles. At larger departments with more personnel, people may specialize. The only way to know is to call the agency you want to work at and ask.

Hypothetical question: if someone died in a brand spankin' new car (very few germs/bacteria, tight seal on the doors and windows) how long would it take for the body to decompose? What would it look like in, say, 75 years?

Asked by Jordy over 9 years ago

Interesting question, but I doubt I can be of much help. A body can do one of two things after death--decompose or desiccate. So it might turn into sludge or it might become a mummy. It might depend on temperature or pH levels (more relevant if the car was buried) to determine which way it would go. Being sealed would definitely slow the process to a crawl. I had a body in an attic once that was partially wrapped in plastic, and after three years the wrapped areas still had plenty of flesh and the unwrapped parts were down to bone.

I asked a question a few minutes ago, but what I really meant was if you can take the case and analyze the evidence as well?

Asked by Alyne about 9 years ago

Yes, we do it every day.

What are the major responsibilities of your job?

Asked by Violet over 9 years ago

I spend about 90% of my time sitting in front of a computer looking at fingerprints. The rest of the time I go to crime scenes to photograph and process for fingerprints and collect items of evidence. When I was at the coroner's office I probably spent 40% of the time examining victim's clothing, 10% on gunshot residue testing, 30% on hairs and fibers, and 20% everything else. 

can someone make their own fingerprints disapper from their own hands

Asked by fierce95@yahoo.com about 9 years ago

Temporarily, with sandpaper or chemicals, but they will grow back in the same pattern.
