Forensic Scientist

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.

Hello im currently a senior high school student and i always wanted to be a forensic scientist. How do you become one? As in what course should i take ? And is medical technology a good option?

Asked by Star over 8 years ago

It all depends on where you want to work and what they require. At the coroner's office we all had at least a bachelor's degree in a natural science like biology, because there were not any forensic degrees then. If you want to be a DNA analyst you will probably need to major in genetics or biochemistry. At the police department where I work, with our very small lab, we are only required to have a high school diploma--but you get extra points in the interview process for advanced degrees so we all have at least a bachelor's.I don’t know how helpful medical technology would be because that is specifically geared toward a different profession.

I’m trying to use a dna detection kit (phosphate) to test a stain for semen. How old does the stain need to be for it to turn positive(blue/purple)? The stains could be 6mo. to a year old. on Berber carpet.

Many thanks

Asked by PH about 8 years ago

That’s hard to say. It depends not only on how old the stain is but how old or how sensitive the reagents are. I’ve had old known semen stains not react with relatively new reagents so it is possible.

What is the difference between a forensic psychologist and a criminal psychologist?

Asked by soph02 almost 8 years ago

I apologize but I have absolutely no idea. I suspect there may not be a difference.

I am conducting a research assignment for my Writing 222 class and wanted to site a source off of my own interview. I was wondering if you would mind answering a few questions through email. If you're interested please email me at jennahr45@gmail.com

Sure, I'll email you.

Also this girl touched my phone and phone case, and its been 6 months. I remember cleaning my phone with water and my case with soap. I still feel like after 6 months, this persons dna is on my phone.. I have been using my phone for 6 month

Asked by Helena about 8 years ago

Bleach will also destroy DNA but of course that may damage items. Soap and water will do.

How long does an iPhone have to be submerged in lake water before it can’t be used to find locations or contacts?

Asked by J.H. Paree over 7 years ago

I have absolutely no idea. I asked my coworker (who does digital forensics) this one time because I wanted to get rid of some old phones, but she didn't know either. I smashed them with a hammer and then soaked them in my pool for about ten minutes, but of course I have no way to know if that completely worked.

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 about 8 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.
