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 types of skills for you need for this job?

Asked by kenzie over 8 years ago

A background in science, patience, and attention to detail.

I’m trying to use a dna detection kit (phosphate) to test a stain for semen. How old does the stain need to be for it to turn positive(blue/purple)? The stains could be 6mo. to a year old. on Berber carpet.

Many thanks

Asked by PH over 8 years ago

That’s hard to say. It depends not only on how old the stain is but how old or how sensitive the reagents are. I’ve had old known semen stains not react with relatively new reagents so it is possible.

With respect to drug profiling, could you please explain why it is necessary to have a full understanding of the chemistry of drug synthesis?

Asked by Laura about 8 years ago

I'm sorry but I've never worked in toxicology.

I’m positive that there was a lot of sexual activity in a bedroom. Therefore, there must be evidence of semen somewhere, right? Even if the person tried to be “as clean” as possible there must be drops leftover. How do u scour room to find evidence?

Asked by PH13 over 8 years ago

Sorry for the delay, I’ve been on vacation. I guess it depends where the activity took place. If it all took place in bed and they washed the sheets, then there may not be any to find. An alternate light source can look for possible spots of semen, but the problem is many things can fluoresce, such as vaginal secretions, sweat, saliva, cleaners, certain fibers, etc.

Hello I have a question about forensic science, I am a senior in high school and I want to know what are the steps to take to be a forensic scientist

Asked by Jessica over 8 years ago

titles and job requirements aren't uniform, so the only way to know is to call the crime labs in your area or whereever you might be interested in working and ask them. At the coroner's office we had to have at least a bachelor's in a natural science (this was before they had forensic science majors). At the police department where I am now, they only require a high school diploma but you get more points in the interviewing process for having a four year degree, so we all have one. You can also go on the websites for professional organizations such as the American Academy of Forensic Sciences and check out their job vacancy postings and see what the various positions require. Good luck.

How long does an iPhone have to be submerged in lake water before it can’t be used to find locations or contacts?

Asked by J.H. Paree almost 8 years ago

I have absolutely no idea. I asked my coworker (who does digital forensics) this one time because I wanted to get rid of some old phones, but she didn't know either. I smashed them with a hammer and then soaked them in my pool for about ten minutes, but of course I have no way to know if that completely worked.

What is the difference between a forensic psychologist and a criminal psychologist?

Asked by soph02 over 8 years ago

I apologize but I have absolutely no idea. I suspect there may not be a difference.
