On April 4, the Jing'an Public Security Bureau received a report stating that two individuals had a physical altercation in a neighborhood on Yangqu Road. According to the initial investigation, when the nucleic acid test was about to conclude that day, Jie Mou Rong (male, 65 years old), while maintaining order for the neighborhood test, noticed that his nephew's son, Xue Mou Wei, was late and littering. Jie, acting as an elder, criticized him, which led to a physical confrontation between the two. After the two were separated by nearby residents, Jie suddenly collapsed and was unresponsive. Despite being rushed to the hospital, he was unable to be revived and was pronounced dead.
