An Alabama teenager has been charged with capital murder in the fatal shooting of his high school classmate, authorities said Thursday.

Steven Chase Lafoy, 17, called 911 around 3:30 a.m. Wednesday to report a shooting, Trussville police said in a statement.

Officers responding to the home found Trent Thomas Parkerson, 18, dead in a locked car with a single gunshot wound to the head, Det. Ben Short said.

Investigators said they believe a fight broke out over an alleged theft and Parkerson was shot as he was trying to leave. A rifle was recovered nearby, according to police.

Lafoy was arrested at the scene and was being held at the Jefferson County Jail Thursday on a $500,000 bond.

It was unclear whether he has an attorney who can comment on his behalf.

Parkerson was a varsity wrestler and a defensive end on the football team at Hewitt-Trussville High School.

Football head coach Josh Floyd said coaches have reached out to team members and will work with them “through the grieving process.”
