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.

How long does saliva DNA stay on an object? In other words, for how long the DNA is detectable?

Asked by Aj about 5 years ago

That depends entirely on the circumstances. If a sample of anything--blood, saliva, semen--is properly dried and kept in relatively dry conditions at a steady low temperature, or even frozen, it can last for decades. If the temperature and humidity vary greatly, then the sample could break down. If it's stored in plastic or airtight when wet it could rot and decompose.

Does it help my chances of employment if I am a certified peace officer? I know your a civilian but if having the added peace officer certification along with everything else does it help, hurt, or make no difference? Plus I get to carry a gun and badge

Asked by Parker almost 6 years ago

I would think it would help because it would show some familiarity with law enforcement agency procedures. Even if you work for a completely civilian agency such as a medical examiner’s office, you would still be interacting with law enforcement constantly, so I would think it would help. Though even if you can carry a gun and badge in your everyday life, you probably wouldn’t be able to carry it on the job unless it was all right with your employer.

I mean a sworn police officer sorry for not being specific

Asked by Terry over 5 years ago

As far as the job is concerned, I would think the odds of getting the job would be the same, but there are other considerations. The pay and benefits are different (at least at my agency) between sworn and civilian because they’re different unions. A sworn officer would be taking less pay and benefits to be non-sworn so the hiring party might wonder why, or worry that they would get tired of it and want to leave.

I need to know how can I get blood group from old dried blood?

Asked by Mou over 5 years ago

They used to do that in serology, taking threads soaked in the blood and putting them in tiny pools of blood type reagents. I don’t know exactly what the reagents were, sorry, that had never been part of my duties. But if you research old serological techniques you should find it.

Best of luck!

What level math do you actually need and use?

Asked by Elizabeth G. over 5 years ago

It depends on what you want to do. I've always used only basic addition, division etc., for calculating reagents. Accident reconstruction would probably require a bit more and maybe DNA analysis, but I don't really know. Best of luck!

Biggest pet peeve out of co workers? I also heard working at police and sherif departments your lunch is always stolen is this true?

Asked by Mike over 5 years ago

That's never happened to me at the police department, but then there's only my forensic unit with access to our refrigerator so it's not a problem. But it used to happen in the lunch room at the coroner's office all the time! I injected candy with hot sauce once. That stopped it for about a week.

How do you do a ride along?

Asked by Cale over 5 years ago

Contact your local PD and ask what their procedure is. You will probably have to fill out an application and a waiver. Best of luck!
