Earlier on Sunday, two men in their 30s were fatally shot in an apparent walk-up attack at a San Diego park, according to police.

Police responded to a report of gunfire at about 1:30 p.m. at Mountain View Park, San Diego police Officer Dino Delimitros said. The park is near the intersection of Ocean View Boulevard and 40th Street in the Mountain View neighborhood.
