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'm sorry but I would not have the slightest idea. It would depend entirely on the path of the bullet and what it hit. Sorry I couldn't help!

whats the most challenging thing about your job?

Asked by kenia almost 8 years ago

Worrying that I might have missed a piece of evidence at a crime scene or in a lab process.

Many cold cases have unidentified victims but how come they are unidentified when you have fingerprints and hair, etc, i don't understand why cant they know who they are when they have that.

Asked by lily almost 8 years ago

Because not everyone's fingerprints are in a database. You only have fingerprints taken when you are arrested or apply for a job or some other license for which it is required. Not all of those necessarily end up in a database accessible to the agency that has the unidentified person. And DNA such as hair only helps when you have a profile to compare it to--if the unidentified person is a convicted felon so their DNA might have been entered when they went to prison, or if there are family members available to give a sample (in which case you would have to already have an idea of who the person might be). It's not really like TV. We don't have databases of every single person and every single substance known to man.

Do you have any advice on how to prepare for this job

Asked by Angel over 8 years ago

Take all the science courses you can, and visit and talk to forensic science personnel. You'll find them very approachable.

i asked a question and didnt even realize i forgot to put my teachers email so il just give you mine (derektclamon@gmail.com) thank you!

Asked by trace clamon over 8 years ago

Okay, I emailed you.

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 8 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!

Thanks again! So scattering hair over a crime scene would not cover the more commonly found searched for nuclear DNA? meaning the criminals in the movie (Charles town) arn't achieving much protection at all?

Asked by lisa fan over 8 years ago

It could help if it's pulled hair, not cut, and if they were super-careful to leave no fingerprints or any other kind of possible DNA samples so that the police had no choice but to test the hairs for possible suspect DNA. It would also depend on the scene--if it's a heavily traveled bank, for instance, so there is a ton of discarded hairs, the police would hardly test them all. If they leave a tuft of hair on say, a chain-link fence used to get away, where the police couldn't help but notice it, then they'd have a better chance of making it a useful diversion.
