What Happened

On a fateful night in October 2020, 29-year-old Alberto Arenas, a mentally ill man, was shot and killed in his own backyard by Los Angeles County Sheriff's Department (LASD) deputies. The incident began when a neighbor called the police to report fireworks being set off in the area. Unbeknownst to the responding officers, Arenas was experiencing a mental health crisis and was in possession of an airsoft rifle, which resembled a real gun but fired plastic pellets.

Deputies from the LASD, including Deputy David Acosta, responded to the call and encountered Arenas in his backyard. Despite being informed by the neighbor that Arenas was mentally ill and may have been in distress, the deputies chose to use lethal force, shooting and killing him. The family of Alberto Arenas has since spoken out, stating that he needed help and support, not deadly force.

The incident has raised questions about the use of force by law enforcement, particularly in situations involving individuals with mental illnesses. The LASD has faced criticism for its handling of the situation, with many arguing that deputies should have used de-escalation techniques and sought to provide Arenas with the help he needed.
