An arrest has been made in connection with the deadly shooting at Tuskegee University in Alabama that killed an 18-year-old and injured at least 16 early Sunday.

Jaquez Myrick, 25, of Montgomery, was charged with possession of a machine gun, according to authorities, who said he was found leaving the scene of the shooting.

The mortal barrage of shots erupted around 1:40 a.m. on the Macon County campus as the school’s centennial festivities were winding down, authorities said.

La’Tavion Johnson was identified Sunday evening as the teen who died in the shooting, according to the Macon County Coroner’s Office.

Police said 12 people were injured when they were hit by gunfire, while four others were injured during the incident, some as they fled to hide.

Several videos posted to social media captured what looked like numerous gunshots and showed people diving to the ground or taking cover in vehicles.

A statement released Sunday by the Alabama law enforcement agency announcing the arrest did not indicate whether authorities were still searching for other suspects, but it called on the public to continue sending in tips. relevant to the FBI.

According to radio transmissions from police officers sent to campus to investigate the shooting, it was initially suspected that there were multiple shooters.

“There are going to be two shooters at this time, maybe more,” an officer said in a radio call, according to transmissions provided by Broadcastify.

In a university statement Sunday morning, Johnson was identified only as a “non-academic person.” The statement also stated that the individual’s parents had been informed.

“Several others, including Tuskegee University students, were injured and are being treated at East Alabama Medical Center in Opelika and Baptist South Hospital in Montgomery,” the statement continued.

State police added hours later that the person killed in the shooting was 18 years old. Shortly before midnight Sunday, Johnson’s name was released.

At the request of the Macon County Sheriff’s Office, special agents with the ALEA Bureau of Investigation were investigating the shooting Sunday.

“Special agents are still gathering and reviewing information relating to the sequence of events that ultimately led to the shooting,” ALEA said.

Authorities asked anyone with information about the shooting to contact investigators immediately. Authorities also asked potential witnesses to upload any digital files from the incident, including videos, to the FBI.

University officials said it was “finalizing student accountability and notifying parents.”

“Further updates will be provided as more information becomes available,” the university added.

Tuskegee University canceled classes Monday and announced that grief counselors would be available for students in the school’s chapel.
