20 14 At 9: 30 pm on June 29th, Mr. Jia, a citizen of Hubei Province, rode an electric car to take his wife and two children home. When passing through Doumen District Library, suddenly something like darts came from the roadside. After hitting his wife's bag, he bounced off his daughter's head and stabbed a small wound. The daughter cried only once and immediately fell into a coma. After more than ten minutes, she was taken to the hospital. She was not breathing and her pupils were dilated.

A poisonous needle suddenly came from across the street and almost killed his three-year-old daughter. Mr. Jia, who has worked in Doumen District of Zhuhai for many years, was scared all day yesterday. At present, the police have filed a case for investigation, and the forensic doctor initially judged that the substance contained in the poison needle is succinylcholine, which is a chemical substance that can cause respiratory muscle paralysis. If the amount is large, it will be fatal.
