Pittsburg High student arrested in fatal shooting

A 17-year-old Pittsburg High School student was arrested in class Monday in connection with a shooting at a gathering that killed a man and injured two others, police said.

The suspect, whose name wasn’t released because of his age, was being held at Contra Costa County Juvenile Hall on suspicion of murder, said Pittsburg police Capt. Ron Raman.

Just after 10 p.m. Sunday, a gunman confronted three men who were standing on the street in front of a home on the 200 block of Auburn Drive for a “social gathering,” Raman said.

The gunman, who was not a part of the get-together, shot the three men and then took off before police arrived, Raman said.

All three victims, who were only identified as Pittsburg residents, were taken to hospitals, where one of the men, Anthony Valdez, 19, of Pittsburg later died. The other victims were in stable condition, police said.
