DADEVILLE, Ala. – Authorities in Alabama were imploring people to come forward with information Sunday about a shooting that killed four people and injured 28 others during a teenager’s birthday party.

The shooting happened at a birthday party in downtown Dadeville at around 10:30 p.m., Sgt. Jeremy Burkett of the Alabama Law Enforcement Agency said. There was no initial confirmation about what led to the shooting, and Burkett did not identify a suspect but said the person is no longer a threat to the community.

“There were four lives tragically lost in this incident and there’s been a multitude of injuries,” Burkett said during a news conference Sunday.

Burkett said 28 individuals had sustained a “wide variety of injuries” during the shooting with some in critical condition. Fifteen teenagers were reportedly treated for gunshot wounds at Dadeville’s Lake Martin Community Hospital, hospital spokesperson Heidi Smith told media outlets.

Of the 15 teens, six have been treated and released while nine have been transferred to other medical facilities, Smith told CNN. Five of the hospitalized teens were in critical condition and four were stable. Some victims were flown to a trauma center in Birmingham, Alabama, according to NPR. 

The shootings rocked the city of 3,200 residents, which is about 57 miles northeast of Montgomery, Alabama. The gunfire erupted in Mahogany Masterpiece dance studio, which was converted from the old Bank of Dadeville two years ago.
