Man shot by deputies in Stevenson Ranch allegedly brandished ‘long gun’

Authorities Monday identified a man allegedly armed with a firearm who died after he was shot at by deputies at a residence in Stevenson Ranch, and an investigation was underway to determine if he shot himself.

Christopher Mosco, 32, of Stevenson Ranch, died at the scene of the shooting, the Los Angeles County coroner’s office reported. An autopsy was pending.

Deputies received a “family disturbance” call about 3:30 p.m. Sunday from the 24900 block of Chicory Court, according to Deputy Tracy Koerner of the Sheriff’s Information Bureau.

“The call stated a male at the location was acting erratic,” Koerner said. “The call was updated stating the male was now suicidal.”

Arriving deputies saw the man in a second-story window armed with “a long gun,” Koerner said.

“Deputies attempted to gain his compliance and repeatedly told him to lay down his weapon,” Koerner said. “During the contact, the suspect pointed his weapon at the deputies and a deputy-involved shooting occurred at approximately 4:23 p.m.”

Deputies went into the home to render aid to the man and discovered he had a gunshot wound to his upper body, Koerner said. Despite life-saving measures taken by deputies and paramedics, the man was pronounced dead at the scene. A firearm was recovered at the scene.

“At this time, it is undetermined if the suspect’s gunshot wound was self-inflicted or a result from the deputies firing their weapons,” Koerner said.
