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.

a car VW jetta traveling at 30 or 40 mph hits a 67" tall 160 pound woman how far will she be thrown.

Asked by Sarah over 8 years ago

I'm sorry but I have no idea. You'd have to ask an accident investigator.

If you were given a 20GB hard drive that had been used to image an 8GB USB device and
found during analysis that more than the 8GB image was on the disk, what would this
indicate? How would you then proceed?

Asked by Parbh over 8 years ago

I have no idea, so I asked my co-worker. She said:My first question would be was the 20GB forensic wiped? Was it completely empty when the 8GB was put on it?Second, does the software that you use to image produce working files or executable programs that are needed to view the image? Otherwise 8 GB is 8 GB so there can't be more.

When looking at a murder scene, could you simpky check the body for fecal matter or urine in their groin area to see if that is where the murder took place?

Asked by Quincy almost 8 years ago

I think you mean to check for that wherever they're lying to see if the body had been moved?

Well, not everyone evacuates upon death. Also the clothing absorbs most of it, and any that leaks through could also have leaked through after being moved. But yes, that could be an indication that the body had been moved just as bloodstains would.

Hope that helps!

Can you test for how long dna evidence is present. Like if I cut myself on accident three days ago could you time stamp that without me telling you how long ago the accident happened.

Asked by PF over 8 years ago

No. There is no time stamp on DNA, so far as I know.

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 about 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!

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 .
