A man wounded last week in a shooting at Rincon Indian Reservation has died of his injuries, and charges against the suspected gunman have been upgraded to include a murder count, authorities reported Wednesday.
Jason Gillespie, 46, was pronounced dead at a hospital about 11:30 p.m. Monday, according to the San Diego County Sheriff's Department.
Deputies responding to a report of gunfire about 1 p.m. Friday found Gillespie wounded in the 7500 block of Mendoza Road, about a half-mile northeast of Harrah's Resort Southern California, Lt. Joseph Jarjura said.
The suspected shooter, probationer Kyle Del Gregory, 31, was arrested at the scene.
