PALMETTO -- Authorities are investigating the death of a Palmetto High School student-athlete on Thursday afternoon.
About 5 p.m., authorities and paramedics responded to a residence in the 1900 block of 24th Avenue West in Palmetto.
Initially, officials believe Kyle O'Halloran, 18, had been shot in the head. But later Palmetto police said they were unsure if the man's injuries were caused by a gunshot or some other trauma when he hit the ground.
A car pulled into the driveway and when the victim approached the car, there was some sort of altercation. The victim hit the ground as the car was driven away, police said.
The Manatee County Homicide Task Force is on the scene, but officials have not yet ruled the death a homicide.
O'Halloran was a member of the Palmetto High football team, playing fullback and linebacker. He also won the discus competition in the Manatee County Track and Field Championships last April.
Other details were not immediately available.
