Unlike finicky fingerprints and frowned-upon fiber analysis, DNA evidence has been the most bulletproof evidence for forensic sciences in recent years. But staffers at a research firm in Israel have recently upended the presumed infallibility of this forensics golden child—by making it themselves.

Nucleix, a Tel-Aviv-based life sciences company, was able to create credible DNA evidence that could be used to finger the wrong person, proof that even genetic evidence can be manipulated (beyond planting a hair or used cigarette) just like other physical traces.

"You can just engineer a crime scene," Nucleix founder Dan Frumkin told The New York Times. "The current forensic procedure fails to distinguish between such samples of blood, saliva, and touched surfaces with artificial DNA, and corresponding samples with in vivo generated (natural) DNA," Frumkin and co-authors wrote in a recent Forensic Science International: Genetics study that announced the technological achievement.
