A teenage girl was fatally shot and three others were hurt Friday night during a party in Jacksonville, Florida, officials said.
One of the injured was in life-threatening condition, while the others two had non-life-threatening wounds, the Jacksonville Sheriff's Office said.
Authorities did not have anyone in custody, and said they were looking for one suspect.
The shooting happened during a "gathering outside one of the apartments" in Jacksonville's Brentwood neighborhood, Jacksonville Sheriff's Office Sgt. Craig Waldrup said.
"There was some loud music. An argument ensued and someone in there, someone shot some people," Waldrup told NBC affiliate First Coast News.
The victims' names were not released.
Another teen was injured in a separate shooting in Jacksonville on Friday night, police said. The girl was in serious condition after being shot at a birthday party, authorities told the station.
And earlier this week, seven people were injured when more than 50 shots were fired in Jacksonville's Eureka Gardens apartment.
