Because of his suspicion that his ex-girlfriend was humiliated by the owner of a painting studio while she was learning to paint, a 26-year-old man from Hefei killed the owner's entire family. At noon on July 10, a homicide occurred in the Yangtze Art Garden studio on Huaihe Road Pedestrian Street in Hefei city. Zhu Yunyu, suspect of the crime, stabbed to death three people from the Huo family (the owner of the painting studio) as well as a ten-year-old boy who was visiting the Huo family at that time. The tragedy has drawn attention from netizens. Under thorough "human flesh search", Zhu Yunyu's Tianya account and QQ space were exposed one after another. By tracing his accounts, netizens discovered that Zhu Yunyu had posted online a year ago about his girlfriend being humiliated. He also asked questions on Tianya, hoping that netizens could provide him with information about Huo Houyun.
