Missing person finder tech

BoingBoing reader Pierre Nel in South Africa says,

A news story is airing on South African television & radio about a locally designed system that enables people to track down missing kids using a dna sample (like a single strand of hair etc) – according to various parents that appeared on the news the system actually works, but the company that invented the device don't want to release any details on exactly how the device works, because it's still in a "testing phase". We were treated to some satellite images on the news story though. Weird.
