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.

Why don’t they let civilians interview suspects?

Asked by Jessica almost 5 years ago

Because that's not our job. That's the detective's job. They're in charge of and responsible for the investigation.

How often do homeless people intentionally try to get arrested? I heard they do this because the shelters won’t take them if they are on drugs among other things so they commit crimes in front of cops to have a place to sleep

Asked by How often do homeless people intentionally try to get arrested? I heard they do this because the shelters won’t take them if they are on drugs among other things so they commit crimes in front of cops to have a place to sleep about 4 years ago

I wouldn't be involved with cases like this so I don't know. In my experience with homeless camps the people are usually not too cooperative and don't want to leave, so I haven't seen this happen.

At a postmortem crime scene where hair has fallen out from the victim, over time, is all the loose hair collected for evidence or just some of it

Asked by Leesa about 4 years ago

That would depend a great deal on the circumstances. Any hair actually on the victim that does not appear to belong to the victim would likely be collected. If there was obviously a struggle, if the victim was beaten or strangled, hairs on their hands or caught in their fingers would warrant special attention or any clumps of hair nearby. If the victim's lying on a carpet that apparently hasn't been vacuumed for the past decade, then single hairs might be disregarded. If the person is outside and shot from a distance, then hairs would likely be disregarded.

I hope that helps!

I have my first interview out of college for a forensic chemist position. Do you have any tips for a first timer? Are there any questions I should really prepare for?

Asked by MIKE about 4 years ago

Wow, best of luck!! I would suggest you Google the heck out of the facility and find out everything you can about what they do—if it’s a state lab, what kind of evidence they accept from the state agencies. They probably test for illegal drugs, but are they testing the actual drugs seized, or bodily fluids from arrested people, or blood/urine/gastric samples from medical examiners or coroners offices—or all three. If you can’t find the information then that’s a good and reasonable question to ask. They’re sure to ask you what kind of instrumentation you’ve worked with, in class or in an internship, etc.—GC Mass Spec, IR, etc., how much experience and what kind of samples you tested. PS If it’s not posted you might want to ask about hours and/or overtime. They might be 9-5 M-F or they might be 24/7, depending on the size and location.

Best of luck!!

Hi, I’m writing a novel in which a tape-and-murder victim’s remains are found after ten or twenty years outdoors in rural New England. Could investigators find the perp’s dna at that point?

Asked by Laurel over 4 years ago

On the victim’s body? Most likely not because after that much time the victim would most likely be skeletal remains only, if buried and certainly if on the surface. If the body was in some kind of container, sealed, it might be completely decomposed, mummified or preserved, depending on circumstances. If the killer’s blood or semen got on some object that was with the body, it could conceivably survive if protected, but it would be very unlikely to yield a usable DNA profile.

Hope that helps!!

What is the worst part of your job? What is the best part? How do u cope with the stress of the job/the dead bodies etc?

Asked by Niamh about 4 years ago

What is your favorite part of this job?All the interesting, different, bizarre stories that make up the crimes that have happened that we have to investigate. 



What is you least favorite part of the job?Being 'on call' and knowing you can be interrupted at any moment of the day and have to go to a crime scene, even if it's the middle of the night or a holiday. I've also had to change vacations because I have to testify in a trial. I hate that. 

Being around the dead is something you either get used to really quickly or you don't. The dead will not bother you, but the living can drive you crazy! And stress depends where you work. I have a great office and a relatively low-crime area, so unless we have a lot all happen at once, which is not too often, it's really not that stressful. If I lived in a more hectic place with too many demands and not enough time or resources, it might be a different story.



What has been discovered or invented by you or other people who work in the field of forensics?
What is something I could tell my class and teachers that would surprise them about forensics?

Asked by Ella over 4 years ago

"Touch" DNA or "Contact DNA" can obtain a profile from an item that someone merely touched: https://en.wikipedia.org/wiki/Touch_DNA

I would say Rapid DNA, which can provide a profile in less than two hours and used in the battlefield, but that's been around since 2014.

And though you've seen it on TV every day for 50 years, it has not been possible for the average latent print examiner to scan in a fingerprint and search every person who's ever been fingerprinted, including job applicants and military. Most databases would be just county or state wide, and may or may not include job applicants (or staff) depending on the preferences of the agency, and certainly not the military, ICE or Interpol. At my department we only got the ability to remotely search the FBI database last year.

Hope that helps!
