Our hearts sympathize with everyone who is scarred by this tragedy, and no one will expect such trauma when starting a new day."
They made their opinion in the statement, saying that it's wise to understand the origins of various events first, including: the cause of the stabbing of a policeman and the death of a 47-year-old scientist at the University of California, Berkeley.
The case occurred on the afternoon of March 3. Police officers from the San Diego County Police Department showed Li Yan the expulsion documents, and Li Yan confronted the police officers with a kitchen knife. Li Yan then closed the apartment door and the police officers asked for reinforcements.
When the police were waiting for more support, a staff member in the apartment building told them that Li Yan threatened a repair worker with a knife the day before. Police officers tried to communicate with Li Yan for about 45 minutes, but she was unable to cooperate with the police.
At about 1:30 p.m. that day, the staff opened the apartment door. In the chaos, Li Yan then raided and stabbed a police officer with a police dog. The police officer was injured and fell in the lobby aisle outside the apartment. Li Yan rushed out of the apartment, causing the police officer to shoot several shots.
