“Time Travel” Murder & DNA Evidence

“DNA retrieval techniques are now so sensitive that simply lightly touching an object – such as a door knob or knife handle – can leave enough of a trace to carry out a successful DNA analysis.”

From a privacy perspective, the idea that someone can pull my DNA off any object I’ve ever touched is just a touch unsettling.

From a forensic perspective, this opens other challenges. Like in this BBC article, where a forensic scientist explains how a mix-up in forensic procedure caused police to chase a murderer who was herself already dead.

…so, not only can they get your DNA off a doorknob, but “Brazil”-style “Tuttle bugs” are alive and well…?
