UT Shooting, First Gunman Down, Searching for Second Gunman

A gunman wearing a ski mask and carrying a rifle entered the University of Texas library this morning, firing several shots before taking his own life. Police are now looking for a second possible suspect as the campus has been put on lockdown.

According to ABC:

Police are currently clearing every building on campus looking for a second suspect who is described as wearing a beanie and carrying a long rifle.

"We are working the possibility of a second suspect," said UT police chief Robert Dawson. "We're trying to eliminate that possibility."

An email and text alert was sent to students and faculty around 8 a.m. Central Time, just as the day's first classes were beginning, warning that an "armed subject was reported last seen at Perry Castaneda Library" and telling students to remain in place.

"I was walking to class, a little late," senior Robby Reeb told ABCNews.com. "I was walking from the business school, and a guy sprinted past me screaming, 'There's a guy with a gun.' I looked up and saw a man in a ski mask, wearing a suit, and carrying an assault rifle. And I called 911."
