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.

Sure, no problem. Please email me at lisa-black@live.com.

Hi! I was wondering something about timing. Say a kidnapping takes place in a hotel room. How long is the room cordoned off? At what point is the evidence collected and taken away? When can the room be let again? (Working on a novel!)

Asked by Nico over 6 years ago

We’ll hold the scene as long as we need to get everything done, and that could be a day or two or three, but for a kidnapping it probably wouldn’t be more than a day, just enough to collect all the victim’s stuff, and collect fingerprints, hairs, fibers, anything that might belong to the kidnapper. We eventually get tired and want to go home (though we can go and come back, so long as it hasn’t been ‘released’) and the police department don’t really want to hold it longer then absolutely necessary, because they have a cop or two sitting there doing nothing but guarding the scene, and it takes them off the road. Hope that helps!

Can a decades-old used latex condom buried with a body still have dna evidence in it that can be tested?

Asked by J.J. White over 6 years ago

If it were allowed to dry and kept dry, then it's possible, though the odds would be incredibly slim since the decomposition fluids from the body would most like overwhelm it. It's worth a try.

Hi, so how do you get used to blood and gore?

Asked by Crazy over 6 years ago

You just do. Somehow you can either tolerate it or you can't, or you learn to cope with it. There are cops who can work homicide for thirty years and still have a weak stomach. They just don't let it keep them from doing their jobs.

Which, in your opinion, is the most effective in solving crime on a daily basis: DNA analysis, Fingerprint analysis or Luminol (or other) spray testing?

Asked by Eliza almost 7 years ago

Luminal and dye stains just enhance or show you where things are, like blood or fingerprints. DNA analysis and fingerprint analysis are equally effective, so you use what you have. You might have DNA at a crime scene but no fingerprints, or vice versa. We don’t get a choice of what’s left at a crime scene, so we have to make the most of whatever is there. Given that, whatever is the most effective is whatever gives you information relevant to the crime. Say there’s a smear of the victim’s blood on the suspect’s shirt. The suspect tells police he found the body and tried to administer CPR. In that case, the DNA is very much there, but useless to solve the crime. If the suspect says he never met the victim and the same shirt is found in the suspect’s closet , then that’s very relevant to solving the crime.

Do you see yourself doing this job in the next ten years?

Yes.

I have not used cocaine in a year, why is my hair still testing positive for cocaine?

Asked by Terence J Donnelly about 7 years ago

Hair is just dead cells, so once something is there, it stays there. Hair grows at about 1/2 inch per month, in general (mine, to my frustration, grows much more slowly). So if your hair is longer than say 6 inches, the cocaine will still be there. If your hair is much shorter, then I don’t know what’s happening.Hope that helps.
