Leech Helps Solve Crime

Today, a man was convicted of robbing an elderly woman's home because of a leech. The robber's name is Peter Alec Cannon. Eight years ago, he and an accomplice robbed an elderly woman's home. When police arrived at the crime scene, they found little evidence except for a leech that appeared to have just bitten someone on the floor. None of the police officers had any bite marks on them, and neither did the elderly woman, so the police assumed it was from one of the robbers. They took DNA from the blood inside the leech and put it into the database. Last year he was picked up on a drug offense. The officers cross-checked his DNA against a database and found the blood that was extracted from the leech. I think it's really cool that a leech could actually help solve a crime. A lot of people think leeches are really disgusting, because they stick onto you and suck your blood. But I think it's awesome that they can actually help people too. I also wonder what other animals might have accidentally contributed to the solving of a crime.\
