Catalytic converter theft suspect fatally stabbed by South El Monte homeowner: LASD

SOUTH EL MONTE, Calif. - Los Angeles County investigators said a South El Monte homeowner took matters into his own hands when he interrupted an alleged catalytic converter theft in progress early Friday morning.

Authorities said the incident occurred just before 3 a.m. at a home in the 11200 block of Thienes Avenue.

The homeowner told deputies with the Los Angeles County Sheriff's Department he was sleeping when he heard a group of men talking in his driveway. In response, he grabbed a kitchen knife and went to confront the group of up to four burglars who were reportedly in the process of stealing a catalytic converter from his vehicle parked in the driveway. At some point during the confrontation, investigators said the homeowner stabbed one of the suspects, identified Saturday as Juan Alarcon.
