I was wondering, do people have different patterns on each finger? One finger tented arch, one plain arch sort of thing?

Asked by Amelia H. over 9 years ago

Yes, absolutely. Most people will have a mix of patterns on their fingers.

Hi. Will a combination of chlorine bleach, gasoline and paint thinner destroy blood DNA?
Thank you :)

Asked by Ayden about 9 years ago

As far as I know, the chlorine bleach alone will do it.

So unless the gloves and/or surface had some form of dirt or oil or other sort of substance that would make a print form, if both were completely spotless, there would be no gloveprints?

Asked by R-Mod almost 9 years ago

Probably not. Fingerprints are left usually because skin has oils and sweat, which of course gloves wouldn't have.

Asked by john34 over 8 years ago

I haven’t worked any really crazy ones, and sorry but any semi crazy ones would take too long to explain.

Hi I have a job interview tomorrow. Can you tell me the difference about criminal justice DNA and crime Scene DNA? And also what would you do if two samples where switched or contaminated in the lab? And what types of questions came up in interview?

Asked by Jen about 9 years ago

I don't know what you mean by that--DNA is DNA. Samples being switched is one situation, and contaminated is another. Obviously the situation would have to be remedied and the samples re-analyzed. Questions will probably be a combination of general interview questions such as 'what are your strengths' and questions about your specific training and experience in forensic topics. Good luck!

Please email me, I have tried to learn Forensics for my child's case, due to the Law lacking in Preserving and Safe Guarding evidence and lacking any witness statemnets although there was alit of people as potential witnesses?

Asked by Brandy about 9 years ago

Witness statements would be included with the officer's work, not the forensics unit. I'm sorry for your loss. Is there a victim's advocate at the police department that handled the crash that could help you? They could walk you through where to find all the information you want. You didn't include your email address.

If a deceased is found on a soft surface such as a bed with no lividity or rigor mortis, what can be said about the estimated time of death?

Asked by Erica M over 9 years ago

Whether a surface is soft or hard wouldn't affect the presence of lividity or rigor mortis, they would develop regardless. It might affect the pattern of lividity (whiter at the pressure points).
