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 do you like best about this job

Asked by Angel over 9 years ago

All the interesting, different, bizarre stories that make up the crimes that have happened that we have to investigate. 

Can a forensic examiner analyzing evidence distinguish between a latent fingerprint from a bare hand and those produced by someone wearing gloves?

Asked by kayla lions over 8 years ago

Sure, because fingerprints will have ridges and gloves will not.

How to chemically distinguish between an original hand-written signature and a printed copy (the one that is scanned and then printed)

Asked by rixy over 9 years ago

I'm sure document examiners could do this fairly easily but I don't know exactly how. I would guess that alternative light source (like infrared or ultraviolet spectrums) could show that there is no difference between the signature and the rest of the document. Or I believe thin-layer chromatography could show that the chemical makeup is the same. A Questioned Document Examiner could tell you much more.

Can extensive bruising be caused by pushing someone with the palm of the hands on the chest area

Asked by Jay about 9 years ago

I'm not a doctor but I don't see why not. If the flesh and muscle is being crushed between the ribs and the person's hands, that would have to cause damage. Sometimes CPR can cause cracked ribs.

Discuss how the following statements can both be true when applied to forensic investigation: “Every contact leaves a trace” AND “Absence of evidence is not evidence of absence.”

Asked by Sara over 9 years ago

Why does this sound like a homework question?

Do you ever get to go to a crime scene?

Asked by Emily about 9 years ago

Yes, all the time. That's part of my job. But that will depend on what your job is, some people work only in the lab, and others work only at crime scenes.

I was wondering if the dna from different sources are the same, for example is the dna the exact same in sweat, hair, saliva etc? I ask because I once saw a movie where the criminals threw hair over a crime scene, ruining all the DNA?

Asked by Lisa Fan over 9 years ago

Your nuclear DNA is the same in the skin cells holding your hair in place, your saliva, your blood, your skin, your bone marrow etc. Your friend's DNA is of course different from yours, but the same in their saliva, their blood etc. The criminals probably threw someone else's hair around the crime scene so it wouldn't match them.
