On the morning of 1 June 2010, just before 10:00 a.m., 46-year-old Zhu Jun entered the Lingling District People's Court in Lingling, Yongzhou, Hunan Province, China. Armed with a submachine gun and two pistols, he opened fire at an office on the fourth floor of the courthouse, shooting people who happened to be present at the time.
The attack killed three judicial workers: presiding judge Zhao Hulin, deputy chief judge Jiang Qidong, and court clerk Huang Lan. Three additional people were injured in the shooting. According to available reporting, the victims who were killed were not discussing any case connected to the assailant; the shooting appears to have been indiscriminate against those present in the office rather than targeted at specific individuals involved in his personal legal matter.
Zhu Jun killed himself following the attack, ending the incident without a trial or prosecution.
Reporting on the motive indicates that Zhu was angry at the Chinese justice system in connection with the outcome of his divorce settlement. He had a son, and had been separated from his wife for three years prior to the shooting. At the time of the attack, Zhu worked as the head of security at the Postal Savings Bank of China's Lingling District Branch. He is reported to have obtained the weapons used in the attack from post office security personnel by falsely claiming that he needed to take the weapons to be examined.
Because the sole identified assailant died at the scene by suicide, no criminal charges were filed and there was no subsequent prosecution or trial. The case is treated as resolved in terms of identifying the person responsible, though the underlying grievance driving the attack — dissatisfaction with a divorce-related court outcome — was not itself adjudicated as a separate matter following the shooting.
