Ohio State University says the ex-employee who killed himself inside a gallery at the campus' contemporary art museum was a security guard who resigned in 2009 to avoid being fired.

In a statement Monday the university identified him as 63-year-old Dean Sturgis. The school says he had worked as an unarmed security guard, but no other details about his employment were released.

No one else was injured in the shooting, which was reported at 11:20 a.m. Sunday at the Wexner Center for the Arts on the sprawling Columbus campus. It happened shortly after the museum was scheduled to open for the day.

Sturgis apparently vandalized artwork before he shot himself. Wexner Center officials are still assessing the damage.
