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.

I am writing a paranormal suspense thriller novel and I need to know if you could figure out a person's identity in 2010 if all you had were the eyeballs and they were preserved since the 1970s.

Asked by Yvonne Schuchart almost 8 years ago

My guess would be no. I would think the formaldehyde would destroy the DNA in the cells, though I don’t know for sure, and in any event they weren’t doing DNA in the 70’s so you’d have to find something of the person’s to compare the eyeball DNA. If you have something of the person’s retained from the 70’s, especially hair for example, perhaps there is mitochondrial DNA in some cell in the eyeballs that could still be obtained and compared to the mDNA from the hair.Otherwise I doubt ophthalmologists would take or save retinal scans back in the 70’s. Hope that helps. Best of luck!

Hi so I'm doing a school project on a career I want to do and I was wondering if there was any chance I was able to ask you questions about Forensic science and pathology?

Good afternoon Lisa!

I am currently taking a classes to earn my Bachelor's in Forensic Science, I just had some questions regarding your job now and how you went about getting your degree. Do you have an email were could communicate?

Thank you!

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 about 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.

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 about 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.

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 8 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).
