The police of Fuzhou city, Fujian province, southeastern China last week announced the rare case on the social network WeChat. Accordingly, the police on June 11 received a report of a burglar breaking into and taking many valuable properties at an apartment in Fuzhou.
When police investigated the scene, they discovered that the thief had broken into the apartment from the balcony. After entering the apartment, this person cooked egg noodles to eat before burning mosquito incense, covered the owner’s blanket and slept overnight.
Police found two fresh bloodied mosquitoes on the living room wall. They identified the blood stain as the suspect’s and sent it for a DNA test.
Test results showed that the DNA from the blood stain on the mosquito carcass matched the DNA of a man surnamed Chai. The suspect was arrested on June 30 and admitted to the break-in, as well as four other burglaries.
Many people commented on the post of Fuzhou police, expressing surprise that the police relied on evidence on mosquito corpses to find suspects. “It’s the revenge of mosquitoes, I was wrong to think they are useless,” one person wrote.
DNA is an important tool to help Chinese police solve crimes. Police in eastern China’s Zhejiang province in June arrested a woman who threw a cob from a high-rise to the head of an eight-month-old baby, after extracting DNA from a saliva sample on the cob.
