In more than a year, more than 20 consecutive rapes and gang rapes occurred in a middle school in Taihe County, and more than 10 people were involved. After this extra large criminal gang was broken up, three suspects were sentenced to death and two were sentenced to life imprisonment. As the investigation of the case went deeper, the police found that Tao Tao (a pseudonym), who had been a "model student" for many years, was also involved in several cases.
