A 15-year-old girl working on a family farm was shot in the back from a stray bullet and investigators are trying to determine where the shot originated.

The 15-year-old is expected to recover from her gunshot wound. At this point the bullet has not been removed, which leaves investigators clueless as to what type of gun was fired.

The shooting was reported to the Stanislaus County Sheriff’s Department around 3:15 p.m. Sunday at a farm that is off Marshall Road in Crows Landing. The farm is about a quarter mile east of the Turlock Sportsman Club, said sheriff spokesman Sgt. Anthony Bejaran.

Sheriff’s investigators spoke to the members at the club that day and inspected all the guns, Bejaran said.

The club members were not the only shooters that day, however. There were people on the northwest corner of the San Joaquin River who had also been shooting, Bejaran said. The identity of those individuals and the types of guns they were shooting is unknown to investigators.

“At this point we don’t know where the bullet came from and it’s possible we may never know,” Bejaran said. “Without the round we can’t determine the type of gun used.”

It is not illegal to shoot guns from the riverbank, as long as the people are not trespassing, Bejaran said.

Bejaran said this was the first report of an errant round striking a person in that area.

“It appears the shooting was unintentional,” Bejaran said.

Investigators are hoping to speak to the individuals that were shooting from the riverbank. Anyone with information about the shooting is asked to contact the sheriff’s department at 525-7114.
