A late Sunday night meeting in the parking lot of McGavock High School turned into a shooting that killed an 18-year-old man and injured his male relative, Nashville police said.

Hermitage precinct detectives have identified the victim as Brandon J. Adams of S. New Hope Road.

Adams was a standout basketball player at Nashville charter school LEAD Academy, where he helped lead the Panthers to consecutive 20-win seasons.

“I think it took a lot of people by surprise,” said Adams’ former coach Matt Barksdale, who is now the head basketball coach at Centennial High School in Roswell, Ga. “He was great. I can’t say a bad word about him.”

Adams, who garnered all-state honors as a senior last season, averaged a team-leading 16.9 points and 5.4 rebounds per game while helping lead the District 7-A and Region 4-A runner-up Panthers to a 25-6 record.

“He was one of the hardest workers I had on the team,” Barksdale added. “The kid flat out worked his butt off day in and day out for two years. He went from being a junior getting spot minutes to an all-state player as a senior. He was just the hardest worker.”

Adams' death marks the 70th reported homicide in Nashville this year.

An investigation shows that Adams and a relative rode to the school in a Honda Civic to meet other individuals. Police did not specify the nature of the meeting in a news release.

Adams and his relative arrived first and parked on the right side of the school, near the softball fields. The other vehicle pulled beside theirs.

Police say an occupant of the other vehicle got into the backseat of the Honda Adams was driving. A second occupant of the other vehicle got out and threatened Adams and his relative with a pistol.

As Adams sped off, the gunman began shooting, police say, hitting Adams several times. The Honda crashed near McGavock Pike.

Adams was taken to Skyline Medical Center, where he died. His relative was treated for a graze wound.

The person in the backseat is believed to have fled just prior or after the crash, police said.

The suspects are described as two young men wearing hoodies and sweatpants.

Anyone with information is asked to contact Crime Stoppers at 615-742-7463.
