David Erickson, 61, of Anaheim, California, was found dead of gunshot wounds inside a home on West Greenleaf Avenue on August 31, 2021. Erickson, a Marine Corps veteran who later worked as a diesel mechanic, was discovered after police responded to a report that a man had been shot.

When officers arrived they were confronted by an armed man identified as 55-year-old Robert Nelson, also of Anaheim. An officer-involved shooting followed; Nelson was killed at the scene. The Anaheim Police Department and the Orange County District Attorney’s Office opened investigations into Erickson’s death and the officers’ use of lethal force.

Authorities have not disclosed a motive or whether Erickson and Nelson knew each other prior to the shooting. Does anyone have information about Erickson, his last known contacts, or the events that led to that 911 call?
