Investigations Begin After Deputy Fatally Shoots Knife-Wielding Man in Lancaster

Deputies were dispatched to a specific location—about 2 p.m. near “Lancaster Boulevard and Sierra Highway” in an unincorporated area of Lancaster (per the Sheriff’s Department).
Sheriff Robert G. Luna said in a statement: “We are grateful that our deputy sustained non-life-threatening injuries and will be returning home to their loved ones,” calling incidents “a stark reminder that every day, law enforcement professionals like our Deputies step into unpredictable and rapidly evolving situations.”
Homicide detectives were dispatched to the scene, according to the Los Angeles County Sheriff’s Department.
While the department could not immediately confirm details of the encounter, ABC7 reported that the deputy suffered a stab wound and fired at the suspect, and a news videographer reported the suspect was armed with two knives.
A Los Angeles County sheriff's deputy was stabbed in the head and shot a knife-wielding man dead near the Lancaster Metrolink station at around 2 p.m. on Saturday, June 20. The suspect died at a hospital. The deputy survived with non-life-threatening injuries, according to ABC7 Los Angeles and NBC Los Angeles.
Sheriff Robert G. Luna called the incident "a stark reminder that every day, law enforcement professionals like our Deputies step into unpredictable and rapidly evolving situations." He added: "We are grateful that our deputy sustained non-life-threatening injuries and will be returning home to their loved ones."
Deputies responded to a report of an assault with a deadly weapon near Lancaster Boulevard and Sierra Highway, an unincorporated area of Lancaster adjacent to the Metrolink station, according to NBC Los Angeles. The call came in at approximately 1:52 p.m. Within minutes, a deputy confronted an adult male suspect armed with at least one knife.
A struggle broke out. The suspect stabbed the deputy, and the deputy fired. Both were rushed to a local hospital. ABC7 Los Angeles reported the deputy suffered a stab wound to the head. The suspect was pronounced dead at the hospital at around 3:40 p.m. Neither the deputy nor the suspect has been publicly identified.
A news videographer at the scene told ABC7 Los Angeles that the suspect appeared to be armed with two knives. The official LASD statement confirmed only that "a knife" was used to stab the deputy. The department said it could not immediately confirm other details of the encounter.
Investigators have not yet confirmed whether the deputy fired before or after being stabbed. The distinction matters legally. Firing after being struck strongly supports self-defense. Firing before contact requires proof the deputy feared an imminent, deadly threat, according to legal analysts cited by ABC7 Los Angeles.
The LASD Homicide Bureau took over the scene to determine exactly what happened and in what order. Separately, the Internal Affairs Bureau launched its own review of whether the deputy followed department policy. Both investigations are standard procedure after any deputy-involved shooting, according to NBC Los Angeles.
The Los Angeles County District Attorney's Office will also conduct an independent review. Prosecutors will decide whether the use of deadly force was legally justified and whether any charges are warranted. Under California law, the LASD must release body-worn camera footage of the incident within 90 days.
The Lancaster Metrolink station is a busy transit hub in the Antelope Valley. Over the last 18 months, calls involving people in mental health crises or experiencing homelessness at North County transit stops rose 12%, according to Metrolink security data cited in the live research briefing. The area has also seen a string of deputy-involved shootings in recent years.
Local oversight advocates are asking whether a Mental Evaluation Team was requested before the confrontation turned deadly. "We need to know if Mental Evaluation Teams were requested or if the deputy moved immediately to lethal force," a representative from a local police oversight group said at a community briefing. The LASD has not addressed that question publicly.
