Spokesman Ray Garner told reporters in Huntsville, Alabama, that the shooter was caught outside a science building in the campus. But the spokesman declined to identify the shooter or the victims.

According to the spokesman, five of the victims, including all three of those killed and two of the injured, were faculty members of the university. The third injured was a staff member. No students were involved in the incident.

Local hospital officials said two of those injured were in critical conditions.

The shooting took place at a biology faculty meeting at the university's Huntsville campus. The suspect was reportedly denied tenure on Friday afternoon, which prompted the shooting. But the exact cause of the incident has not yet been confirmed.

The Huntsville campus, which has more than 7,000 students, was closed Friday night and all students were advised to go home.
