The BBC reports that in Finland, a car thief was identified from his DNA — DNA taken from blood found in a mosquito inside the stolen car.
Finding the car in Seinaejoki, north of Helsinki, police saw that the mosquito had recently sucked blood and decided to send the insect for analysis.
The DNA found from laboratory tests matched a man on the police register.
