Finnish police said it was rare for them to use insects to solve crimes, although they are interested in everything found at a crime scene.
"It is not usual to use mosquitoes. In training we were not told to keep an eye on mosquitoes at crime scenes," Palomaeki said, laughing.
"It is not easy to find a small mosquito in a car, this just shows how thorough the crime scene investigation was," he added.
The suspect has been questioned and insists that he rode in the car when he was picked up hitchhiking, but did not steal the car. Link -Thanks, Geekazoid!
