An 18-year-old woman was killed and at least six other people were injured in a shooting at a birthday party in California early Sunday, authorities said.
Officers were dispatched to a home in Antioch just before 1 a.m. (4 a.m. ET) Sunday for "numerous" 911 calls reporting multiple gunshots fired, the Antioch Police Department said in a news release.
Officers found multiple victims outside, surrounded by a large crowd, police said.
Officers were told that partygoers had gathered at the residence to celebrate the birthday of a 19-year-old man.
"During the party, multiple shots were fired after some uninvited guests arrived," police said. The shooting "created a panic," sending attendees, including gunshot victims, fleeing in multiple directions, with some victims driving themselves to local hospitals, authorities said.
One of the victims, an 18-year-old woman, was taken to a local hospital but did not survive her injuries, police said. Authorities have yet to publicly identify her.
Four women and two men ages 18 to 20 sustained non-life-threatening injuries, authorities said.
Police said the shooter or shooters fled in a vehicle and remained at large.
The Antioch police Investigations Bureau responded to the scene and took over the investigation, police said. They asked anyone with information to come forward.
