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.

what is the importance of physical fingerprinting in a scientific sphere of DNA profiling?

Asked by Nic over 7 years ago

I”m sorry but I don’t understand the question. What is physical fingerprinting and what is a scientific sphere?

Which is better to be forensic scientist, forensic science in the middle and low university or biology in the good university?

Asked by Kim over 7 years ago

It may depend on what you want to do. If you want to work crime scene, then you might be a more attractive candidate with all the hands-on practical work of a forensic science degree. But if you want to be a DNA analyst, then I’d go with biology. Best thing to do is call the labs where you might someday apply and ask them. Best of luck!

Hello! How easy is it to collect finger prints, scan them and identify a match (I imagine its very hard) but out of say 100 cases how many could actually be solved using fingerprint analysis?

Asked by Eliza almost 7 years ago

Generally about a 6 to 10% identified rate is good. Many prints that are collected at scenes by officers are ‘not of value for comparison ‘ (smudges or only have a few ridges) and many that are good belong to the victim or their friends, family, employees etc.

How long will latent prints last when ninhydrin is used?

Asked by Krissy almost 7 years ago

I'm not sure what you mean: a) how long after a print is left will ninhydrin still detect it, in which case I can say from my own experiment that there's little rhyme or reason to this, sometimes older prints develop better than newer ones or vice versa, or b) how long does a print developed with ninhydrin last, and the answer to that is that ninhydrin is a dark purple dye, so it is permanent, though it will continue to develop so that the entire page may eventually turn purple so we use a fixative chemical on the now-visible print so that will stop the ninhydrin from darkening the paper further. I hope that helps!

HI! Did you ever regret pursuing your job? Also, can you be both, a forensic scientist and a CSI?

Asked by Fenis over 6 years ago

No, I've never regretted it. And your job title is whatever your agency says it is, so 'forensic scientist' and 'csi' can mean different things in different agencies, so you can certainly be both. the first implies you work mostly in the lab and the second implies you work mostly in the field, but depending on the size of the agency and any specialization you have, you might do both equally or they might be completely separate.

What is the regular intern day/night shift?

Asked by Crime Scene Investigator over 7 years ago

We don't have a set schedule for interns. They'll come in on weekdays, but other than that we work with their school/work schedule.

Where you ever shocked by a crime scene?

Asked by Denise_ot5 over 7 years ago

They’re all shocking, in their way, But there hasn’t been one in particular that bowled me over.
