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.

Can you test for how long dna evidence is present. Like if I cut myself on accident three days ago could you time stamp that without me telling you how long ago the accident happened.

Asked by PF almost 10 years ago

No. There is no time stamp on DNA, so far as I know.

How long does it take to really get a fingerprint match if using all available databases?

Asked by Seeker over 10 years ago

That depends entirely on your digital situation. How big is the database (how many fingerprints does it have to search through), are you searching both fingers and palms, how many servers or whatever can you devote to the task, and have the search parameters been narrowed down, say to only right hand fingers or only the left index. All those factors will affect it so that a search could take anywhere from a few seconds to a day .

My brother was killed. I believe he was murdered. His left arm was nearly severed from his body and his left mastoid process was crushed. The blood at the scene was descibed as an 8in in diameter patch. How much blood should have been at the scene?

Asked by autumndawn over 10 years ago

I'm sorry to hear about your brother. Unfortunately I have no idea how much blood there should be, you'd have to ask a pathologist, but from my experience I can guess it would depend on two things--what kind of surface was he on--concrete, tile, carpet, dirt? Also, how long the heart kept pumping after the injury. I have seen gunshot victims where they barely bled at all, and others were completely soaked practically head to toe. So there are a number of factors that will affect this.

Hello, my name is Maria and I'm currently a High School senior. For my college and career project I need to interview someone in my field of interest which is forensics. Is it possible I could interview you through FaceTime or something? Thank you:)

Is a forensic expert allowed 2 make a hair or fiber match based only in the fact that the hairs or fibers were artificially dyed

Asked by Michele over 10 years ago

Unlike what you see on TV, a hair and fiber expert never 'matches' hairs or fibers (except in the case of DNA analysis). We can say they are 'consistent with' having come from this person or this article of clothing in that all the microscopic characteristics are the same or within a group of the same characteristics. Though dyed hair is quite distinctive with the growth since dying and the color so it would be a strong indication that they came from the same person, you couldn't actually put a number on it (like 'there's a one in two billion chance this came from someone else', like DNA). That's largely why hair and fiber comparisons are rarely done any more.

Have you ever done wax reconstruction to a person whose face was messed up? Is it likely u could mold a face with the person before they die, could u put a wax figure in the casket and it would pass for a dead person.

Asked by Brandy Daugherty about 10 years ago

I have not because I am not trained in facial construction. We did have a case in which we had a reconstruction done on a skull which helped identify the person. As for the casket, I don't see why not, depending upon the skill of the wax worker.

Hi, i am currently studying a degree in forensic science, i just wanted to know if you have any knowledge of different techniques used around the world in crime scene environments. Specifically between the Netherlands and the uk.

Asked by Ryan Williamson about 10 years ago

That's a good question but I'm afraid I have no idea since I've never worked anywhere except the U.S. I would guess that the scientific techniques would all be basically the same but the administrative aspects (paperwork, how reports are worded, what is done in which types of cases etc.) would vary.
