A former student at Temp University shot a student campus security officer two times before turning the gun on himself in an apparent domestic dispute that turned violent on the Philadelphia university's campus.

The suspect shot Cori Miller, his ex-girlfriend, once in the right eye and once in chest as she worked her post as a student campus security officer at a classroom and administrative building. Miller, a junior at the university, was hospitalized after the incident in serious but stable condition, but was expected to survive.

The gunman, 21-year-old Shawn Walker, who was enrolled at Temple about year ago before dropping out, died at the scene of self-inflicted gunshot wounds, according to police.

Walker and Miller, who reportedly had dated on and off for several years, had been seen walking together peacefully on the way to Miller's job, according to witness reports. There were no reports of arguing or conflict.

Police believe Walker escorted Miller to her post at Vivacqua Hall, went to a nearby doughnut shop and returned to shoot her.
