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. about 9 years ago

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

If a man masturbates a few times on a towel...And his girl friend urinates on it and then wipes her self down there with it. Would it be possible to find semen in or around her vagina?

Asked by Brian over 9 years ago

I really don't know--I suppose it's possible but I don't know how urinating on it would affect it. I also don't know why one would urinate on a towel. And it sounds like you're trying to find an innocent explanation for your girlfriend's parents on the occasion of her unexpected pregnancy. Either way,, good luck.

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 over 8 years ago

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

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

Is there a kind of gloves that doesn't leave gloveprints? Asking for a sort of detective story.

Asked by R-Mod over 8 years ago

Sorry I didn't answer this before, I'm on the road. I've seen glove prints occasionally--a remarkable number of burglars don't bother to use them. But I've never compared the prints to a particular glove because by definition gloves are mass produced and therefore not unique like fingerprints. I've seen ones from cloth gloves, which will leave the knit pattern behind, or latex gloves which will sort of look like a group of random bubbles crammed together.

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!
