4 teens shot, 1 killed outside a birthday party in Houston

(CNN) — Four teenagers were shot and one was killed early Sunday morning after a fight broke out in a parking lot outside a 16th birthday party in Texas.

Police responded to a Houston production studio around midnight Saturday after multiple people were involved in a dispute which escalated into gunfire among the group, Harris County Sheriff Ed Gonzalez tweeted.

As many as 100 people were involved in the fighting in the parking lot when the shooting began, according to CNN affiliate KHOU. “A large number of spent shell casings were discovered in multiple areas of the parking lot,” the Harris County Sheriff’s Office said in a Sunday news release.

One 17-year-old male died at an area hospital, according to Gonzalez.

Two other 17-year-olds were taken to the hospital, including one who was airlifted to Texas Children’s Hospital, according to the sheriff’s office. The other was treated and released, then taken into custody on an unrelated warrant, the sheriff’s office said.

A 14-year-old girl was also treated for injuries not believed to be life-threatening at an area hospital, the sheriff’s office said. No suspects in the shooting have been identified and the cause of the altercation that preceded the gunfire is unknown, according to Gonzalez.
