Chinese local police has managed to catch a burglar through the DNA analysis of the bloodstain left by a mosquito squashed on the wall in a stolen apartment.

While investigating a burglary in a residential compound in Fuzhou, East China's Fujian Province, the police inferred that the suspect may have stayed overnight after finding some noodles and egg shells left in the kitchen, a piece of lightened mosquito coil, as well as a dead mosquito and two bloodstains on the wall.

Through the bloodstain collection and DNA analysis, the police confirmed they belonged to a suspect surnamed Chai who has a criminal record. Chai was arrested 19 days after the burglary occurred. In one swipe, the police was then also able to solve three other burglary cases all linked to the same man.
