A 17-year-old has been arrested and charged with first-degree murder for the fatal shooting following the Riverdale High School graduation held at Middle Tennessee State University (MTSU) Wednesday, May 18.

Murfreesboro Police Criminal Investigations Division homicide unit has obtained juvenile petitions for first-degree murder for a 17-year-old. Clarksville Police Department officers took him into custody shortly before 4:30 p.m. Thursday, May 19.

The deceased victim has been identified as 18-year-old Hasani Brewer.

The other victim is a 17-year-old. His name will not be released. He is in stable condition.

The preliminary investigation shows Brewer and the 17-year-old victim got into an altercation, and the fight spilled over to the tennis court on the MTSU campus next to the Murphy Center. That’s when the shooter opened fire, killing Brewer, and injuring the 17-year-old.

This occurred as people were leaving the graduation.

“This was not a random shooting,” said Public Information Officer Larry Flowers. “The two victims and the shooter knew each other.”

Charges could also be pending for other known individuals. That part of the investigation continues.

“This is a senseless act of violence that never should have occurred,” Flowers said. “We ask the public to join us in sending prayers to the families during this tragic and difficult time.”

MPD is working closely with Middle Tennessee State University, MTSU Police, Rutherford County Schools, Rutherford County Sheriff’s Office, and the Tennessee Highway Patrol.

The investigation remains active.
