TUSKEGEE, Ala. (AP) — Tuskegee University student Sid Guynn hid under a car when he heard gunshots rip through his Alabama campus in the middle of homecoming celebrations, then ran back to his dorm, frightened by what it looked like a machine gun.

“It was terrifying; I couldn’t find my phone or my brother,” Guynn said. His brother is not a student at the university, he said, and was visiting when the barrage of gunfire sent students diving to the ground or running for their lives.

The shooting left one man dead and injured at least 16 others early Sunday, a dozen of them by gunfire, authorities said. An arrest was announced hours later. Many of the injured were students.

The man killed in the weekend shooting at Tuskegee University has been identified as La’Tavion Johnson, 18, of Troy, Alabama, who was not a student, the local coroner said Monday.

Jaquez Myrick, 25, of Montgomery, was arrested as he left the scene of the campus shooting and was found with a gun with a machine gun conversion device, the Alabama Law Enforcement Agency said. Myrick faces a federal charge of possession of a machine gun, the agency said in a statement. He did not accuse him of using the gun in the shootings and did not provide further details.

The agency did not say whether Myrick was a student at the historically black university, where the shooting erupted as the school’s 100th homecoming week was winding down.

It was not immediately known if Myrick had an attorney who could speak on his behalf. He was being held in the Montgomery County Jail, online booking records show.

Twelve people were wounded by gunfire and four others suffered injuries unrelated to the shootings, the state agency said. Several were being treated at East Alabama Medical Center in Opelika and Baptist South Hospital in Montgomery, the university said in a statement.

Their conditions were not immediately released, but Macon County Coroner Hal Bentley said he understood at least one of the injured people was in critical condition.

The FBI has joined the investigation and said it is seeking tips from the public, as well as any video witnesses may have. He created an online site for people to upload videos. The Bureau of Alcohol, Tobacco, Firearms and Explosives was also involved in the investigation, a local prosecutor said.

The school is no longer an open campus, Tuskegee University President Dr. Mark A. Brown at a news conference Monday outside the campus’ main entrance. All students and faculty will be required to carry ID while on campus.

Brown said there were security checks at all official school events, but the party where the shooting occurred was not school-sanctioned.

“We did not and could not have planned security at an event that was not pre-approved or sanctioned by the university,” Brown said. But he said the school administration will “take full responsibility” for “implementation of corrective actions”.

The former head of campus security has been replaced, the president said, and the new security chief will conduct a thorough review of the shooting. When asked, Brown did not provide the name of the new head of campus security.

Brown said classes have been canceled for Monday and Tuesday, all students will be offered counseling and there will be a town hall to address community concerns.

All resident students “near shot” will have an opportunity to move, Brown said.

The shooting is the latest case in which a “machine gun conversion device” was found, something law enforcement officers across the nation have expressed serious concern about. Proliferation of these types of weapons is possible through small pieces of metal or plastic made with a 3D printer or ordered online.

Guns with conversion devices have been used in several mass shootings, including one that left four dead at a Sweet Sixteen party in Alabama last year and another that killed six people in a bar district in Sacramento, California .

“It takes two or three seconds to insert some of these devices into a firearm to instantly turn that weapon into a machine gun.” Steve Dettelbach, director of the Bureau of Alcohol, Tobacco, Firearms and Explosives, said in the AP’s gun report earlier this year.

After the shooting at Tuskegee University, Guynn, 18, said school-wide group chats were filled with messages of support for the wounded victims, whom he said he knew personally. He came to Tuskegee this year from his home in Iowa because he wanted to learn in a close-knit black community, he said.

“Tuskegee, it feels like family here,” Guynn said, adding that “everyone is connected.”

The shooting left the entire university community shaken, said Amare’ Hardee, a senior from Tallahassee, Fla., who is president of the student government association.

“This senseless act of violence has touched each and every one of us, directly or indirectly,” he said at the school’s convocation Sunday morning.

Sunday’s standoff comes just over a year after four people were injured in a shooting at a Tuskegee University student housing complex. Two campus visitors were shot and two students were wounded as they tried to leave the scene of what campus officials described as a “unauthorized party” in September 2023, the Montgomery Advertiser reported.

About 3,000 students are enrolled at the university, about 40 miles (64 kilometers) east of Montgomery, Alabama’s capital.

The university was the first historically black college to be designated a Registered National Landmark in 1966. It was also designated a National Historic Site in 1974, according to the school’s website.

Guynn said he hopes more security will prevent future gun violence on campus. He also said he doesn’t want national attention to define the school and community he loves.

“For something like that to happen, it’s not like Tuskegee,” he said.
