It turned out the victim had travelled in his taxi, and he had a medical condition that made him shed a lot of dandruff. A partial DNA match came from a tiny fragment of that dandruff getting caught in the victim's nail polish when she paid her fare. Poor bugger. If his defence hadn't been on the ball, he may well have been convicted. And these types of mix-ups and mis-applications of non-contextually-assessed evidence are threatening to happen more often, as the forensic services are becoming more and more centralised and removed from day-to-day contact with the investigations they're meant to support (as opposed to lead by the nose).
That's why it's important not to break out the pitch forks and torches, or pre-judge any matter that's sub judice.
