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.

So I'm writing a story and want to know if they can test blood against an old sample? By old sample I mean there's a thirteen year difference from when the first sample was taken and the sample presently taken.

Asked by Delaney about 6 years ago

Yes, absolutely. Blood samples can last decades if stored properly. The most important thing is that they’re dried thoroughly right away so there’s no decomposition. After that, they need to be kept away from UV light and at a steady temperature, the lower the better. Frozen is good, or at least refrigerated, but they can even stay at room temperature as long as it doesn’t get too hot or humid.

I am in school for my a.s. in criminology because my school had no alternatives for forensics, I am now 2 semesters away from graduating with my a.s. and my school now has a crime scene technology a.s. degree. Should I change programs or continue?

Asked by Jozalyn almost 5 years ago

That’s a tough question. If you want to work crime scenes, then the cs tech major might be better. If you want to work in the lab, it might not be very important. I would advise you to call the forensic units at the agencies you’d like to apply to and ask their opinion. With either degree, they may more likely place more emphasis on whether the courses had a lot of hands-on experience, if you have any work experience in the field, labs, internships, etc. That’s how my agency would feel.

Best of luck to you!

Can someone create false positive molestation forensic testing by wiping a week old rag with dried semen onto their child

Asked by Queen B almost 5 years ago

I suppose anything’s possible, but it depends on how well a dried stain is going to transfer to anything. usually a dense, dried liquid simply flakes off a surface. Someone could try wetting the rag but I honestly don’t know how well that would work or if at all. Also, whoever is collecting any evidence off that child would have to swab that exact spot. So I can’t say it’s impossible but I would guess it’s unlikely to work. Hope that helps!

Also, what did you think of those cops that went into that politicians office and napped, ate his food, and just made themselves at home during the riot?

Asked by Tina about 6 years ago

I am an expert in some areas of forensic science. I am not an expert in law, public safety policy or our political system.

Hi Lisa. If you had to test residue on an object, and might suspect if to be sodium hypochlorite/bleach residue, what kind of field test could confirm it. Would it be a simple chlorine strip test?

Asked by Arin almost 6 years ago

I’m sorry but I have absolutely no idea. I have never worked in toxicology. Though my coworker did have to research testing for bleach in one of our cases, I will ask her when I get back to work next week.

Wait is your husband the country singer?!

Asked by Tim about 6 years ago

No. That’s the actress Lisa Hartman Black.

What do you think is the worst case you have ever done. What’s the most gruesome, frustrating, or however you define it.

Asked by Mark about 6 years ago

Probably the most raw was a small plane crash.
