Diego Armando Villa, 23, was fatally shot just before midnight on December 31, 2017, in the 3800 block of Teak Street in San Diego’s Mountain View neighborhood. Officers responding to a 911 call found him on the sidewalk with gunshot wounds to the head and arm. He was taken to hospital but died of his injuries and was pronounced dead on January 1, 2018, at about 3:00 p.m.

The San Diego Police Department’s Homicide Unit opened the investigation. No suspects have been identified and the motive remains unclear. Investigators have said the case faces challenges from limited physical evidence and a lack of willing witnesses, and authorities are asking anyone with information to come forward.
