Apparently, according to some scientists, you can engineer a crime scene in such a way as to leave DNA evidence to convict whomever you want:
The scientists fabricated blood and saliva samples containing DNA from a person other than the donor of the blood and saliva. They also showed that if they had access to a DNA profile in a database, they could construct a sample of DNA to match that profile without obtaining any tissue from that person.
“You can just engineer a crime scene,” said Dan Frumkin, lead author of the paper, which has been published online by the journal Forensic Science International: Genetics. “Any biology undergraduate could perform this.”
Obviously few if any crime scenes will be engineered, at least in the near future, but I could see a criminal business popping up where such fabricated DNA might be useful.
But fear not – there’s a reason this has been announced now:
Dr. Frumkin is a founder of Nucleix, a company based in Tel Aviv that has developed a test to distinguish real DNA samples from fake ones that it hopes to sell to forensics laboratories.
I’ll be he does.
Heh … the market works – see a need, fill it and the world will beat a pathway to your door. Well maybe not the world, but at least a few odd forensic labs.
