A 17-year-old girl was killed and five other young people were wounded in a shooting early Saturday morning at a party in Chico, Calif.
No suspects had been publicly identified or detained by Sunday morning.
A 21-year-old man, a 19-year-old man and another 17-year-old girl were hospitalized and in stable condition by Saturday night, authorities said. A 20-year-old man and an 18-year-old man were briefly treated and released from the hospital.
A motive for the shooting is unclear. Though the shooter remained on the loose, police said it was an isolated incident and there was no further threat to the city about 80 miles north of Sacramento.
The shooting occurred at an apartment complex not far from Cal State University in Chico, but none of the victims were students, the university told the Sacramento Bee.
Chico police responded to several party incidents early Saturday morning, according to police chief Billy Aldridge.
Around 12:30 a.m., cops spoke with two people who were injured when a man assaulted them with a bottle and a firearm after they told him to leave a party, Aldridge said. About two hours later, that man was arrested at a different party on suspicion of brandishing a firearm.
Then, at 3:30 a.m., gunfire erupted at the same apartment complex where the man had been detained, according to Aldridge.
It was the fourth straight weekend in which multiple people were wounded in a shooting at a party. On April 15, four people were killed and 32 wounded at a 16th birthday party in Alabama. On April 23, nine teens were wounded in a prom after-party shooting in east Texas.
Last weekend, one person was killed and five others wounded at a house party north of Boston, while two people were killed and four wounded at a prom after-party in Mississippi.
