One victim, a male UCA student, was pronounced dead on the scene while two other victims were taken by ambulance to the hospital. One of the two victims taken to the hospital was also a UCA student and died. The third man, who wasn’t a student, was treated and released.

‘Monday classes are canceled, and students are encouraged to stay in their dorms and apartments, as all residence halls are under lockdown,” The Echo, the student newspaper, reported.

One suspect was in custody though not under arrest, police said during a 1:30 a.m. press conference.

The UCA Web site reported at 10:35 p.m. Sunday that there were four suspects.

There are students who witnessed the shooting.

According to The Echo, Freshman Tyler Carpenter, who lives on the first floor of the all-boys Arkansas Hall, said he heard five shots go off as a man was running out of the hall into the alley.

‘ ‘When the car drove off, I saw the body on the ground,’ Carpenter said. ‘My heart’s beating a lot faster. I’m kinda scared; someone got shot right outside my room.’
