Cale Matthew Miller, 22, is charged with homicide and is currently in the Seminole County jail with no bond.
Public Information Officer Kim Cannaday said multiple cars were at Mullet Lake Park around 11:20 p.m. when gunfire was exchanged. A round fired by Miller, she said, struck 18-year-old Brandon Lee McGolrick, a passenger in a vehicle attempting to flee the scene.
McGolrick was transported to the Central Florida Regional Hospital in Sanford but died as a result of his injuries.
Investigators worked Saturday speaking with witnesses at the scene and examining evidence before charging Miller with homicide.
