A 17-year-old boy was fatally shot at a party in Hilmar on Saturday night, the Merced County Sheriff's Department reported.
The victim was identified as Saul Lopez of Delhi.
No suspects are in custody and details are sketchy.
Sheriff's spokesman Tom MacKenzie said Sunday that deputies learned about the shooting after Lopez was brought by friends to a McDonald's restaurant in Hilmar about 10:30 p.m. Saturday.
Someone there called 911 and deputies responded.
Lopez, who had a gunshot wound to the stomach, was flown to a Modesto hospital, where he died.
Investigators believe the shooting happened at a party in the 22000 block of Bloss Road in Hilmar.
The circumstances leading up to the shooting are unknown, MacKenzie said, adding that witnesses have not been cooperative.
Detectives ask anyone with information about the shooting to call 385-7445. Callers can remain anonymous.
