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.

You are testing a swab that has DNA on it, but you don't know if it's saliva/ skin cells/urin/blood.How long does it take to determine what it is and find out who it belongs to?Which steps do you have to go through and how much does it cost pr test?

Asked by Ayden over 8 years ago

Usually we can assume what kind of cells will be on it depending on where it was collected from—if from a pop can, it will probably have saliva and skin cells. From underwear might have semen. If from a dark stain, probably blood. How long it takes depends on the type of analyses done and the type of DNA testing—STR, ySTR, mitochondrial, etc. It will take at least a day or two, and after that it depends on the lab’s backlog. We send our DNA to a state lab and it will take between a month and four months to get the results back. If detectives or prosecutors want it faster and someone’s budget is willing to pay for it, we can send it to a private, accredited lab and pay for a faster analysis. They can do it in as quickly as three days or up to a week or two depending on what you want to pay for. If you want it in a week it will cost a few thousand dollars—something like $600 a sample plus upcharges for expedited service and an overall charge, if I’m remembering correctly. If you want more like three days it will be more like $5000. That’s for the basic three samples—victim, suspect and questioned sample.

Good afternoon Lisa!

Sure, you can email me at Lisa-black@live.com.

What is the exact name of the job that is involved in collecting evidence and analyzing it, or is there no such thing? Like for example, does a Crime Scene Investigator's job include gathering evidence from the crime scene and later analyzing it?

Asked by Aman over 8 years ago

That’s a good question, because there is no hard and fast rule—your title is whatever your boss says it is. A CSI may work only at crime scenes or may also do any office or lab analysis as well, it depends on how big the unit is and how work is distributed.

Well, according to the movie, as fingerprints leave an oily residue, they found traces of R-12 mixed with it. They also said that the uric acid levels in the eccrine gland residue were inconsistent with a guy with active metabolism. Too far fetched?

Asked by R-Mod over 8 years ago

Yes. Unless they have a crime lab more incredibly equipped than any I've ever visited.

Can you tell the difference between blood from a cut and blood from a hemorrhage under a microscope?

Asked by Carla over 8 years ago

I couldn’t. I don’t know if a pathologist or biologist could.

As an aspiring forensic scientist, do you have any advice or suggestions for me before I enter this career?

Asked by Eric over 8 years ago

Take all the science courses you can and visit labs that do the kind of services you’re interested in.

Okay I am righting a book, and I am looking for a way to describe it from a forensic scientist/analyzer's point of view. the man would die with a caved in skull, holding his brain in one hand, and his wife's heart in the other.

Asked by Paula over 8 years ago

Sorry, I'm having a hard time picturing how what you're describing would be possible.
