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.

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 almost 9 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.

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 about 9 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.

Do you believe that more could be done to improve dna testing

Asked by kerrie dunbar over 9 years ago

Improved in what way?

Hi i am struggling with coming up with a science fair idea and my main interest is in the forensic field and with Dna, I need guidance with an idea on fingerprints or dna analysis... Please and thank you

Asked by stewy over 8 years ago

I would be happy to help you. Please email me off list at lisa-black@live.com and tell me what you need help with, for instance: How involved does this have to be? Do you need to do just a demonstration or an actual experiment?

Hello, I am In high school & I'm doing a project where I have to ask about 8 questions to a forensic scientist, if you are willing to answer them that would be great & if you can email me @breannejanaeruiz@gmail.com that would be even better, thanks!

Asked by Breanne Ruiz about 9 years ago

Sure, I will email you.

how often is DNA/fingerprint evidence actually left behind at crime scenes?

Asked by danielle about 9 years ago

That's impossible to say, since there's no way to know if perhaps it was left but simply not discovered. Perhaps they touched something that didn't appear out of place so we didn't fingerprint it. Perhaps they touched everything but have very dry skin so they didn't leave prints. Perhaps they left DNA on the steering wheel of a stolen crime but we didn't collect it because the state lab doesn't do touch DNA analysis on non-violent crimes. There are too many factors involved.

I can say that burglars cut themselves climbing through broken windows perhaps 2-5% of the time. But only a fraction of burglars break windows, so....

If you were given a 20GB hard drive that had been used to image an 8GB USB device and
found during analysis that more than the 8GB image was on the disk, what would this
indicate? How would you then proceed?

Asked by Parbh almost 9 years ago

I have no idea, so I asked my co-worker. She said:My first question would be was the 20GB forensic wiped? Was it completely empty when the 8GB was put on it?Second, does the software that you use to image produce working files or executable programs that are needed to view the image? Otherwise 8 GB is 8 GB so there can't be more.
