A 15-year-old boy from Florida is facing charges after allegedly shooting a cyclist in the head following a session of smoking marijuana with friends in a parked van.

The teenager, identified as Tommy Lagree Jr., is currently in custody with the Orange County Sheriff’s Office. He faces charges of second-degree murder and illegal possession of a firearm by a minor.

Despite the formal charges being filed recently, authorities report that Lagree voluntarily surrendered to law enforcement shortly after the incident, which occurred in September.

According to law enforcement, on September 26 around 6 p.m., Lagree, alongside at least two others, was inside a parked van located in the 4900 block of Keith Place in Orlando.

An arrest affidavit, as reviewed by Law&Crime, details that the group was smoking marijuana when Lagree displayed a Taurus 9mm handgun that he had tucked into his waistband.

At some point, 17-year-old Jahriel Huertas came upon the scene, and Lagree shot him in the head, authorities said. The individuals who were in the van then all took off running, according to law enforcement.

Deputies were called to the scene, and, when they arrived, found Huertas “lying on the roadway on top of a bicycle suffering from a gunshot wound to the head,” according to the affidavit.

The victim was transported to a nearby hospital, where he was pronounced dead.

Witnesses reported seeing several individuals running from the van, and a law enforcement helicopter located the residence where at least two of them went after the shooting. Deputies responded and eventually detained those individuals.

Not long after the shooting, Lagree “arrived with his attorney, who advised deputies that Lagree had shot someone and was turning himself in,” according to the charging document. The handgun was also seized.

Two of the individuals who were with Lagree before the shooting identified him as the shooter, deputies said.

It is unclear what investigators believe his motive may have been.

Lagree has been charged as an adult. He is expected in court on Dec. 1.
