On May 30, 2023, at approximately 11:56 a.m., officers were dispatched to the area of Livingston Drive and Park Avenue regarding a report of a stabbing.

Police Dispatch received numerous calls for service, with calling parties describing a male adult suspect, armed with a knife, actively assaulting and stabbing people.

Officers arrived within five minutes of the initial call for service. Upon arrival, they located the suspect described by the calling parties. Officers observed the suspect was armed with an unknown weapon. They attempted to de-escalate the situation; however, the suspect began walking away from them. Officers continued to talk with the suspect in an attempt to get him to drop the weapon, however, he then attempted to enter a residential property, at which point the officer-involved shooting occurred.

The suspect sustained a gunshot wound to the upper body. Officers rendered medical aid until the arrival of the Long Beach Fire Department, who transported the suspect to a local hospital.

At this time, the suspect is being identified as a 31-year-old man experiencing homelessness.

The preliminary investigation indicates the suspect was involved in three separate incidents prior to officers’ arrival.

  • The suspect physically assaulted a female adult and a male adult victim in the area of Park Avenue and Livingston Drive. Both victims were treated at the scene by Long Beach Fire for lacerations.
  • The suspect continued walking into Livingston Park and approached a male adult victim holding a child. The suspect assaulted the adult causing the adult and child to both fall to the ground. While the adult victim was on the ground, the suspect stabbed him multiple times in the lower body. Both the adult and child were treated at the scene by Long Beach Fire.
  • The suspect continued walking towards 2nd Street where he encountered an additional male adult victim. He stabbed the victim in the upper body. This victim was transported to a local hospital by Long Beach Fire for a non-life-threatening injury.

Officers later learned the suspect was armed with a screwdriver; it was recovered at the scene of the officer-involved shooting.

No officers were injured. 

All officers were equipped with body-worn cameras, which were activated at the time of the incident. LBPD is in the process of reviewing the footage and will make that available to the public as soon as possible.

As with all officer-involved shooting incidents, the Department will be conducting a full and thorough multi-level review of the incident. The Los Angeles County District Attorney’s Office will conduct an independent investigation of the incident, as they do with all officer-involved shootings that result in injury or death.
