Antioch police say an 18-year-old woman was killed, and six others were wounded in a shooting at a birthday party in California on Sunday (June 11).
The Antioch Police Department said the shooting happened after uninvited guests arrived at a 19-year-old’s birthday party in the Northern California city shortly before 1 a.m.
The gunfire prompted panic among the revelers, who fled in several directions, some with gunshot wounds, police said.
Many of the victims drove themselves to local hospitals, officials said.
When police arrived at the scene of the Antioch shooting, they found a large crowd outside the home and victims of the shooting.
Authorities later determined that seven people were shot, including an 18-year-old woman who died of her injuries at a hospital and has not been identified.
Police have not publicly identified him. The other victims are between 18 and 20, and all suffered gunshot wounds that were not considered life-threatening, police said.
It is not clear who or how many people fired the shots and whether they knew any of the victims. Police did not specify the circumstances that led to the shooting or possible motives.
However, police shared the suspect or suspects fled the area in a vehicle before officers arrived, and detectives were trying to determine who was responsible.
Officers also interviewed witnesses and neighbors and collected evidence following the shooting on Sunday, police revealed.
The tragedy is one of the latest mass shootings where young people have been killed or injured at birthday parties or other otherwise ordinary events.
A mass shooting at an Alabama Sweet 16 party killed four and injured 28.
Eight people, including several children, were killed in the Texas mall massacre.
According to the Gun Violence Archive, there have been 290 mass shootings in the United States since the beginning of the year, which averages more than 1.7 mass shootings per day.
The non-profit organization defines a mass shooting as a shooting where at least four people, excluding the gunman, people are shot.
