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

Asked by Seeker about 9 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 .

How long would it take for a deceased body to drop below 32 degrees centigrade if they were in good health previously and the ambient temp was 17 degrees centigrade. Would the body be cold and blue to touch inside 2 hours?

I'm sorry but I have no idea. That's a question for a pathologist. Sorry I couldn't help!

Would you be able to tell the difference between hair that was taken from a victim's brush (and planted at a crime scene) and hair that just naturally malted? For example, would hair from a hairbrush have more of a root than a malted hair??

Asked by Caroline almost 8 years ago

I don't know what malted means, but I suspect the answer is no. Just brushing hair can pull it out just as in a struggle.

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 almost 9 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.

If the bar code if worn off of a computer and you are trying to figure out what the bar codes numbers were. How can you get the numbers? Cause where the bar code was before it was torn off. It left a lil bit of the code is visible.

Asked by Laray kirker almost 9 years ago

I would try an alternate light source, UV or IR light or even white light with colored filters. That might make it more visible. Other than that, I don't know, sorry. You'd have to ask a document examiner, they might have more techniques for working with paper.

I'm sorry but I am not trained in accident reconstruction. That is a very specialized field. I would have no idea whatsoever.
