(Charlotte, N.C.) — Trystan Andrew Terrell, 22, a former student at the University of North Carolina-Charlotte, is the suspect in a campus shooting that killed two people and wounded several others. Three people are considered to be in critical condition while one other person is in fair condition.

Terrell, a history student, had dropped out from the school this semester.

The shooting at UNCC was first reported at around 6:00 p.m. local time on April 30. Authorities believe that there is only one suspect and there is no ongoing threat.

The two deceased victims are believed to be white males who were students at UNCC. Their names have not been released.

Multiple local stations aired footage of Terrell being brought into Charlotte-Mecklenburg jail. The suspect could be seen grinning while yelling something at the assembled media. UNCC Police Jeff Chief Baker told the media that Terrell was not on “their radar” prior to the shooting. Chief Baker added that “Our officers’ actions saved lives.”

There is no motive being made public to the attack yet. The school is located ten miles northeast of downtown Charlotte. The shooting occurred on the same night as rapper Waka Flocka Flame was due to perform at Jerry Richardson Stadium on campus. The doors for the concert opened at 6 p.m., just before the shooting was first reported. Chief Baker told the media that officers had just finished a briefing about the event when the shooting began.
