AUSTIN, Texas (CBS/KEYE/AP) A witness has described the gunman who police say opened fired inside a University of Texas campus library then fatally shot himself, as investigators search for a possible second suspect.
UT Senior Robby Reeb told ABCNews.com he was rushing through the campus when he saw a man in a ski mask, wearing a suit and carrying an assault rifle.
"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."
The man fired an automatic weapon on the sixth floor of the Perry-Castaneda Library early Tuesday, UT police spokeswoman Rhonda Weldon said.
"He subsequently shot himself. He is deceased," she said, adding that no one else was reported injured.
Austin Police Chief Art Acevedo told a news conference that police also are investigating what he described as a second crime scene outside the library where shots were also fired.
Police were patrolling nearby buildings with bomb-sniffing dogs to hunt for the possible second suspect and make sure no explosives had been left behind.
"What we're doing right is being methodical to eliminate the second suspect," Acevedo said.
No shots were fired by law enforcement, Acevedo said.
