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.

Sample of which body part do you use to perform a dna check of a john doe if you have to

Asked by Mystery over 9 years ago

From live people we usually take a buccal swab from the inside of the mouth. From a deceased person, we can use any part from which we can extract DNA, such as blood, bone, teeth, etc.

I'm writing a short story and would like to know what a body would decompose like after being left unburied in a forest in January, heavy snowfall, and discovered in February? Thank you so much!

Asked by rose over 8 years ago

I'm not an expert in that particular aspect, but I know from experience that it will make a big difference if the area was continuously frozen as opposed to freezing, then thawing, then freezing again and so on. If it was continuously frozen there might not be too much decomposition at all. If it freezes and thaws continuously then it could be quite decomposed, especially if its not covered with anything like dirt or even leaves. Plus under those circumcstances I would expect a lot more animal activity.

Hi. Will a combination of chlorine bleach, gasoline and paint thinner destroy blood DNA?
Thank you :)

Asked by Ayden over 9 years ago

As far as I know, the chlorine bleach alone will do it.



My son was killed a year ago. They ruled his death a suicide by hanging (belt).knew this was bs.thx 2 you answering my question, can you tell me if I can get his record on my own,or do I need an attorney 2 get thm . I tlkd 2 detective, was blown off

Asked by Jennifer bowers about 9 years ago

I'm sorry for your loss. It depends on what you mean by 'record.' You shoudl be able to get a copy of the autopsy report from the Medical Examiner's or Coroner's office. You can get a copy of the police report from the Records department of the police station. I don't know if you could get a copy of all the detective's notes, which would likely be just a few jottings in a notebook, or any notes that they took while speaking to witnesses, etc.--that may vary by department/state. You may have to make a public records request through your city hall, and notes, witness statements, etc. may not qualify as 'public record.' Again, this varies by location. And, speaking from experience, I'm sure it hurts that the detectives are blowing you off, but they are not doing it because they're hiding something or because they don't care. A great many people kill themselves (this came as a major surprise to me when I started in this field) and very, very often family/friends don't want to accept it and insist that it couldn't happen. They are figuring that if they give it some time, acceptance will come. Best of luck to you.

I was wondering, do people have different patterns on each finger? One finger tented arch, one plain arch sort of thing?

Asked by Amelia H. over 9 years ago

Yes, absolutely. Most people will have a mix of patterns on their fingers.

If a deceased is found on a soft surface such as a bed with no lividity or rigor mortis, what can be said about the estimated time of death?

Asked by Erica M over 9 years ago

Whether a surface is soft or hard wouldn't affect the presence of lividity or rigor mortis, they would develop regardless. It might affect the pattern of lividity (whiter at the pressure points).

Hi I have a job interview tomorrow. Can you tell me the difference about criminal justice DNA and crime Scene DNA? And also what would you do if two samples where switched or contaminated in the lab? And what types of questions came up in interview?

Asked by Jen over 9 years ago

I don't know what you mean by that--DNA is DNA. Samples being switched is one situation, and contaminated is another. Obviously the situation would have to be remedied and the samples re-analyzed. Questions will probably be a combination of general interview questions such as 'what are your strengths' and questions about your specific training and experience in forensic topics. Good luck!
