Homicide detectives were searching for clues Monday after a father and son were found shot to death in Golden Hill.
Police officers were called to 30th and C Streets around 9 p.m. on Sunday. They found Darryl Hunter, 49, lying in the street across from Millers Market. His son, Keith Butler, 30, was found dead in a nearby apartment.
Both victims were taken to a hospital where they later died.
Police say the men had been visiting Butler's girlfriend at her apartment when the father decided to leave and Butler walked him to a bus stop.
Police say gunshots were heard about 20 minutes later, and the son ran back to the apartment, where he told his girlfriend to call 911 and then collapsed.
It was not clear who fired the shots or if there was a motive.
