Officers were dispatched to Georgetown Lane at about 11:40 p.m. on a report of shots being fired at a large party.
When they arrived, they found 25-year-old Antioch resident Jonathon Sanchez with a gunshot wound. Moments later, police obtained information about a vehicle that was stopped on East Leland Road in Pittsburg with two more shooting victims in it.
Police learned that a 17-year-old Antioch boy at the party had become involved in a confrontation, during which he was reportedly assaulted.
He called friends to pick him up. When he left with his friends in two separate vehicles, someone shot at one of the vehicles.
Phillip Torres, 23, of South San Francisco, was shot as well as 19-year-old Walnut Creek resident Joshua Sta Iglesia, according to the Police Department. Sanchez, who was sitting in his vehicle in the parking lot when his two friends were shot, was struck by a stray bullet.
All three men were transported by ambulances to an area hospital.
No arrests have been made. Anyone with information about the shootings is asked to call the Antioch Police Department at (925) 778-2441.
