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.

Hypothetical question: if someone died in a brand spankin' new car (very few germs/bacteria, tight seal on the doors and windows) how long would it take for the body to decompose? What would it look like in, say, 75 years?

Asked by Jordy over 9 years ago

Interesting question, but I doubt I can be of much help. A body can do one of two things after death--decompose or desiccate. So it might turn into sludge or it might become a mummy. It might depend on temperature or pH levels (more relevant if the car was buried) to determine which way it would go. Being sealed would definitely slow the process to a crawl. I had a body in an attic once that was partially wrapped in plastic, and after three years the wrapped areas still had plenty of flesh and the unwrapped parts were down to bone.

Would you choose this field if you had to do it over again?

Yes. Unless I could make it as an architect. I would really like that too.

What kind of toxicology is needed to produce evidence of poisoning from chloroganic pesticides and illicit drugs from around 16-17 years ago. A trace unknown substances test? Blood, hair, bone marrow . . . sample? Free at a gov. agency? for a guy.

Asked by Glass over 9 years ago

I'm so sorry but I wouldn't have any idea since I've never worked in toxicology. And since my agency doesn't do it either I don't have anyone to ask.

Okay, so I'm interested in forensic science but..1.)I'm not that great at chemistry and I'm worried that'll get in the way and 2.) My parents aren't sure how much they'd make annually and if it's a secure job..I just don't know if it's a good choice.

How much chemistry you need depends on what type of work you do. As long as you're not actually working in toxicology or DNA, you shouldn't need to be a great chemist as long as you can reliably work with chemicals and combine them properly (like following a recipe). And as long as you are a reliable and honest employee then the job is secure, once you get it, but I will be honest--there's a lot of competition in this field right now so getting into a position might be difficult. You should definitely have a back-up plan.

How often did you encounter gloveprints? Can they be wiped? What are the necessary circumstances for them to exist? I'm asking not to become a murderer, but to help make a roleplaying case for people I know.

Asked by R-Mod over 8 years ago

Not often. Since a glove itself isn't secreting sweat and oils, there's really nothing for it to make a print with until it gets a little dirty or if the surface it's touching is a little dirty.They can be wiped off as easily as any other print.

Hey! Can I major in Criminal justice and still become a forensic scientist? Or do I have to major in Chemistry,Bio,Etc??

Asked by ash almost 9 years ago

The title 'forensic scientist' doesn't mean anything in particular--job titles will vary by the agency. It would be better to major in a natural science or in forensic science so you could get as much lab experience as possible, but the only way to know for sure what the job requirements are is to call the place(s) you want to work and ask.

Greetings. I am writing a murder mystery in which the victim died from a blow to the head. The killer then loaded the body into the back of an SUV, where it lay for perhaps up to 6 hours. Then the killer dumped the body in a location where he was hoping to frame someone.

First question. Several hours after death, could there still be enough blood at the location of the head wound to leave blood evidence at the dump location? Would there be any way for the forensic experts to determine that that blood landed where it did several hours after its owner had died?

Another scenario. What if the killer, in the process of dumping the body, tried to make it look like the victim died in that location by bashing his head, in the vicinity of the wound, on the corner of a dumpster? What kind of evidence might such a maneuver leave?

I hope this question makes sense... Thank you. :)

Asked by CrankyBeach over 9 years ago

First question: My guess is (simply based on experience) is there would still be sticky blood at the head wound enough to smear on stuff, perhaps. It wouldn't be spurting or perhaps even dripping at that point because it should have begun to coagulate. Provided it didn't dry entirely, so the body would need to be in a place that's neither too dry nor too hot and certainly not both. Cool and humid would keep it from drying. The killer might bash the head but there could be a lack of blood spatter or flowing/pooling blood from the wound, since the blood won't be flowing as it would be if the person had still been alive. Also the problem with moving the body is lividity where the blood pools at the lower spots of the body due to gravity (like on the back if the person is lying supine. After several hours it should be fairly noticeable and then if you move the body, the lividity pattern doesn't quite match the position.

Hope that helps!
