Leech Blood DNA Match Solves Crime

Leeches have been invaluable societal tools for centuries. And they are still proving to have use today; the The Daily Mail reports on how a decade-old crime in Australia was solved after police found a leech with the suspect’s blood:

An armed robber has been caught after his DNA was matched with blood from a leech found at the scene of the crime he committed eight years ago.

The creature was the only piece of evidence recovered from a farmhouse ransacked by Peter Cannon and an accomplice. But it was only when Cannon was arrested for a separate crime last year that the DNA match was discovered by Australian police.

It is the oddest way of convicting anyone I have ever been involved in,’ Detective Inspector Mick Johnston said. ‘I have not been able to find any similar cases anywhere in the world – nothing like this at all.’
