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.

What are the most common mistakes a killer/murderer that gets them caught?

Asked by bart white almost 8 years ago

The vast, vast majority of people who kill people didn't plan to kill someone, so they often leave fingerprints, blood, witnesses, text messages, and then come up with some sort of story that sounded good in their head but wouldn't fool a 6 year old.

Hi. Does the crime scene investigator lead the investigation? or does he collect the evidence and analyse it and pass it on to someone who leads the investigation/ interviews witnesses/ searches for the perpetrator etc? I want to work in field

Asked by Justyna almost 8 years ago

Usually, as far as I know, the detective is in charge of the investigation. The CSI doens’t work for them but is there to provide technical support and advice, but ultimately, the detective has the final say. And unlike TV, the detectives are interviewing witnesses and deciding who to arrest. Best of luck!

Can the fingerprints of a living person be taken off a dead human body, namely the skin of the corpse? If so, what are the easiest places for that?

Asked by R-Mod over 7 years ago

Yes. It's not common, but prints have been lifted using superglue or the more recent RTX. The best areas would be those that are smooth, clean and largely free of hair.

Considering gunpowder residue, how is it possible for someone to get it on their hand after simply firing a gun?

Asked by R-Mod about 8 years ago

Gunshot residue can actually refer to two things, gunpowder that flies out of the barrel with the bullet and can land on the victim, and primer residue that can leak out of the back of the bullet cartridge and spray out onto the shooter's hand. But it can also get on the gun or nearby surfaces or people so presence of it on hands does not prove someone fired a gun, and it can wipe off easily so absence of it doesn't prove they did.

If a right handed person shoots himself in right temple with a 9 mm weapon while in a seated position in floor with back resting against bed and head slumped to his left, where is weapon likely to be found?

Asked by Jeannie about 8 years ago

I would guess in his lap or to his right, but it's impossible to know for sure, since you cannot know exactly how the body was positioned or how powerful the load of the bullet might have been.

Is it normal to find a body in odd and scary places like off a cliff or underwater? If so, is it an option to wait to get the body to lab to analyze or do you have to look at it no matter how bizarre the crime scene?

Asked by ubxh about 8 years ago

Most people die in their homes, so that's the 'normal' place to find them, but there are plenty of more unusual incidents as well. It's never scary, though, since when I go there I'm surrounded by cops, EMS workers, possibly firemen, Medical Examiner staff etc. I always observe the body where it is found, since that is my job. The Medical Examiner's or Coroner's office staff examines the body at their lab, so they can choose to come to the scene or not. If the death appears to be straightforward and natural, they will often not come to the scene and simply have the body transported to them.

How long does a blood sample last taken to verify THC content in the specimen? I'm still waiting for results from over 7 months ago.

Asked by Gregory over 8 years ago

I don't know, but it could depend mostly on where the sample was sent and what their backlog is. Some state labs might have a bad backlog. It could also depend on how they prioritize samples.
