One person is dead and two more injured in a shooting outside a football game at a Jacksonville, Florida high school last night, police said. Witnesses stated gunshots rang out about 15 minutes after the end of the game at Raines High School, and then the stadium was placed on lockdown.

A Duval County police officer said the suspect is still at large. The Jacksonville Sheriff’s Office tweeted they are talking to witnesses.

Police have not yet released names of the victims or the suspect.

At least one person could be seen being loaded into an ambulance, witnesses said.

Duval County Superintendent Diane Green said there was heavy security at the game. The two teams playing are rivals.
