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.

how often is DNA/fingerprint evidence actually left behind at crime scenes?

Asked by danielle almost 9 years ago

That's impossible to say, since there's no way to know if perhaps it was left but simply not discovered. Perhaps they touched something that didn't appear out of place so we didn't fingerprint it. Perhaps they touched everything but have very dry skin so they didn't leave prints. Perhaps they left DNA on the steering wheel of a stolen crime but we didn't collect it because the state lab doesn't do touch DNA analysis on non-violent crimes. There are too many factors involved.

I can say that burglars cut themselves climbing through broken windows perhaps 2-5% of the time. But only a fraction of burglars break windows, so....

Hello Ms. Black, I have two questions 1) can those with a past juvenile conviction enter the field of forensics 2) might you be able to put me in touch with a forensic scientist who would do a informational job interview with one of my students?

Asked by SLP almost 9 years ago

Please see earlier answer about convicted felons. But as far as I know it would probably depend on the kind of crime, whether it was a misdemeanor or felony, etc. Many juvenile records can be sealed or expunged as well, so that process could be worth checking out.

You can have your student contact me Via my web site at www.lisa-black.com and I'll try to help!

I'm sorry but I am not trained in accident reconstruction. That is a very specialized field. I would have no idea whatsoever.

I am looking at becoming a DNA analyst working with hair, blood and gunshot residue samples, would it be better to get a degree in Forensic Science or a degree in Biology?

Asked by ssosiak1 over 7 years ago

If you're going to be a DNA analyst, you will probably not be working with gunshot residue as well. DNA labs are tending to want their analysts to have a PhD in genetics and focus solely in that area, but it would be best if you called labs at which you might want to work and make sure. Best of luck.

How long does it take to really get a fingerprint match if using all available databases?

Asked by Seeker almost 9 years ago

That depends entirely on your digital situation. How big is the database (how many fingerprints does it have to search through), are you searching both fingers and palms, how many servers or whatever can you devote to the task, and have the search parameters been narrowed down, say to only right hand fingers or only the left index. All those factors will affect it so that a search could take anywhere from a few seconds to a day .

can you tell the age of pharmaceuticals - specifically Ritalin/methylphenidate - like how many years ago it was made?

Asked by rogernono about 8 years ago

I'm sorry, I wouldn't have any idea. Do you mean dating the actual pills, or once they're in a person's system? If the former I think you'd have to ask a chemist, if the latter, a toxicologist. Sorry I can't help.

So is there a specific test for nuclear DNA versus mitochondrial DNA?

Asked by L.Randolph over 8 years ago

Yes, they are different substances.
