DNA

09/14/2012 4:26 PM

If somebody were to sell their hair for a wig, and the person wearing the wig were to commit a crime, could the person who sold the hair be accused of the crime? What about blood donation? What about other bodily parts and/or fluids?

Hair...possible...very possible.

Blood transfusion? Not very likely in the least.

Nuclear DNA is used for genetic DNA at a crime scene. Nuclear DNA is not found in red blood cells, platelets, or plasma (they have no nucleus). White blood cells are short lived and are usually not even found in blood transfusion products. Those fluids are as pure as the lab can get it, i.e., rich in red blood cells.

Nuclear DNA could be recovered if the person were receiving some sort of assistance with nuclear medicine and you were the unfortunate donor for that criminal. In that case, you're screwed.

What other bodily fluids are you donating to people of the same sex which would make this a concern?

I'm not concerned, just curious, so much weight is attached to DNA evidence nowadays it seems that when they get a match it's conclusive....What about kidneys and hearts and other organs, does the DNA stay the same or change to the current user?

Back in 1995, my wife had a bone marrow transplant with her sister as donor. Naturally this heightened our awareness so we noticed an article about a young guy in the township who had just received one from his sister. The article said that future blood tests would say he was female.

Have to be a pretty incompetent crim (or a very careless innocent bystander) to leave bits of their internal organs lying around . Especially if they were recipients of transplants.

This sounds like the makings for a plot for a investigation type show if it hasn't already been done. Although they could find two sets of DNA one from the wig and the other from the criminal and think two criminals were involved when only one was.

I recall in the movie Gattaca the guy would leave hair and skin cells from someone else on his keyboard and what not to throw them off the track.

For the hair you would require the associated hair follicle.

Sounds like the making of a good book. Or maybe a Hitchcock type movie.

....could the person who sold the hair be accused of the crime?

not just accused but made totally responsible, what with end use responsibilities being placed on most products, the hair donor (the supplier) has to warrant that their hair will not be used in an illegal manner.

The hair donor is guilty as they were "enriched" by the end use in advance.

Just as ammunition manufacturers are guilty of murder and vehicle manufacturers of dangerous driving ......

Without the enabler there would be no crime....

I wish I was joking. Things are pretty sick these days and getting sicker.

What if there was a reward for the criminal, and while escaping the crime scene, the wig fell off and the criminal slipped on it and fell knocking himself unconscious until the cops arrived....would I be eligible for the reward??

No you would not.

You would be liable for the injuries that the socially disadvantaged victim ( ie the "criminal") sustained and for the biohazard cleanup that would be required as a direct consequence of your hair sale.

The "criminal", aka the victim, would be rewarded for providing information leading to the arrest of a human body part trafficker.

Stop trying to wriggle out of this one curly you should have kept your hair! There's more to this than haircut remorse.

On a similar note:

I collect, buy, sell, repair and refurbish vintage cameras and lenses. I recently purchased a nice old Honeywell Pentax Spotmatic from a estate sale. I was told it had been sitting in a closet since sometime in the 1970's, (and judging from it's superior condition I have no reason to doubt that).

Well, there was a half exposed roll of film in the leer. I thought it would be interesting to have it processed, (C-41, can't do at home). However, what if there's some kiddy-porn or something there?

World of shite for Bricky hey!

There could also be some interesting captured moments there.

Ask a cop what you should do.

Hair is simply proteins, not cells with DNA. You must have cells from the hair follicle or other tissue to extract DNA.

If the hair contains part of the hair follicle at the root of the hair a DNA analysis can be be performed.

The reverse has been done, a doctor placed a tube with a patient's DNA in his arm to fool the forensic team. He got away with it for several years.
