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.

When women have been raped and they do a rape test kit, how can forensic scientists determine if the woman was raped or if it was consensual sex?

Asked by Steffaney Espinosa about 7 years ago

The rape kit will only show biological evidence of another person besides the victim. Bruising, injuries and testimony will be used to determine whether it was consensual or not.

I have an ultraviolet flashlight; orange goggles, & phosphate detector kit. Is this all a crime specialist would use to detect semen? The stains I’m finding are not turning purple, yet I’m sure it’s semen. Is there different method/product I can use?

Asked by PH13 almost 7 years ago

It may depend on how fresh the stain is and how fresh your reagents are. Plus just becuase something fluoresces does not mean it’s semen (see answer above).

I applied for a forensic technician position and I have a online interview to do within the next five days what should I expect?

Asked by DeMario about 7 years ago

I would expect it to be like any other interview--they will ask about your education and experience. If there is any practical experience you have, such as lab analyses, fingerprinting, what programs you used, they may ask specific questions about that such as which software did you use, did you use a mass spec or an electron microscope, etc. If there's things you haven't done, you might say you're aware of the theory of, say, bullet trajectory analysis but haven't had any hands-on experience. That's perfectly okay, no one is an expert in everything. Best of luck!

I want to use aconite in a skin cream for the murder "weapon" in my mystery novel. Could he add enough to kill, but not right away?

Asked by Gloria almost 7 years ago

I'm sorry but that's beyond my technical expertise. You need a toxicologist for that one.

Best of luck!

I stumbled across a Forensic Program on FB. I asked them questions and the person on the other side told me that it is okay not to major in a science, but take several science courses. Should I take their word?

Asked by student almost 7 years ago

Every agency will have their own requirements depending on the position and their preferences. For crime scene or to work in an evidence dept, a criminal justice major may be fine. If you can find a forensic science program that may be great. There is no one answer because it depends what positions they have at each agency.

Why is a fingerprint, glass, tire tracks, handwriting, bloodstain or footwear impressions important in a investiagation? Why do these take a more careful analysis than other evidence like DNA?

Asked by lubashka99 almost 7 years ago

Because fingerprints, tire tracks, footwear impressions and sometimes handwriting can, with sufficient individual characteristics, be identified to a specific person or item. (Glass can as well in the case of a 'jigsaw' match, when it physically fits into a piece of evidence.) These analyses require human attention and thorough training and competency and are not quite as simply done as adding a blood sample to a thermocycler for DNA analysis. Explaining DNA analysis takes a highly trained analyst but the actual process is largely automated.
