Ma Jiajue killed four students in Yunnan University. First, Tang was killed on the night of February 13, 2004, Shao Ruijie was killed on February 13, then Yang Kaihong and Gong Bo were killed on February 15, and then fled from Kunming Railway Station. On February 23, 2004, after receiving the alarm, Kunming Public Security Bureau found the bodies of four murdered men in the dormitory cabinets of the student apartment of Yunnan University.
In order to kill his classmates, Ma Jiajue bought a masonry hammer, a black plastic bag and tape paper, and made a fake ID card. On the night of February 13, 2004, when Tang was unprepared, he beat Tang with a stonemason and killed him and hid him in the closet. Then on the night of 14, Shao Ruijie came back from the Internet and was killed by Ma Jiajue and a stonemason while washing his feet. At noon on June 5th, 65438, when Ma Jiajue was dealing with the blood left by the previous night, Yang Kaihong came to Ma Jiajue to play cards, and was brutally killed by the latter by the same means. 15 night, Ma Jiajue tricked Gong Bo into playing cards, and then he was killed.
According to Ma Jiajue's confession, he quarreled with his classmate Shao Ruijie while playing cards, so he held a grudge and had motive to kill. Gong Bo, a classmate, was killed because Shao Ruijie told Ma Jiajue in a quarrel that Ma Jiajue had not invited Gong Bo for his birthday because of his bad personality, so Ma Jiajue killed Gong Bo. Among them, Tang and he didn't have any problems, because they stayed in the dormitory for several days to prevent killing, so they killed Tang first. Classmate Yang Kaihong was killed for going to the dormitory to find Shao Ruijie. At that time, Ma Jiajue was dealing with the blood left by Shao Ruijie, so he killed Yang Kaihong for fear that it would be exposed.
Among them, Shao Ruijie and Ma Jiajue were good friends for three and a half years. Ma Jiajue said that Shao Ruijie's words made him very sad, so he hated Shao Ruijie and killed his heart. Don was killed only because he happened to be in the dormitory. Ma Jiajue said that if other people were in the dormitory, he would still kill him, just because the opportunity came.
Ma Jiajue brutally killed four classmates and was finally punished. It is reported that on April 24th, 2004, Ma Jiajue was sentenced to death by Kunming Intermediate People's Court. During the whole criminal process, Ma Jiajue was determined and fled after killing. Although Ma Jiajue's guilty attitude was good, the circumstances were too bad, so he was not given a lighter punishment. On June 7, 2004, Ma Jiajue was executed according to law.
