News 8 Austin's Tracy Gladden filed the following video report.

It was a somber day back to class for University of Texas students. Tuesday’s gunman rattled the 40-acres.

UT sophomore Colton Tooley, 19, opened fire at the university's main library Tuesday before killing himself. No one was injured during the incident, but it rattled many students and faculty members who were locked down for several hours.

“I saw him, and I heard the gun shots. My first thought was, ‘God, this is not real, not on our campus, not here,’" sophomore Tanisha Bush said.

Wednesday, the university attempted to return to normal. On the steps of the UT Tower, a group of students prayed before going to class Wednesday.

Bush prayed with strangers during Tuesday's chaos.

"We started praying for him and for his family, because we didn’t know if they knew, and we didn’t know if anyone was hurt. At that point, we didn't see anyone, and we hadn’t heard anymore gun shots," she said.

The gunman ended his own life on the sixth floor of the school’s main library. Ryan Thill was supposed to be there, but he overslept.

"I was going to wake up early and go study with a buddy of mine, but thankfully I wasn't there. My plan was to get there at 7 a.m. and this happened at 8 p.m. I understand that that guy was probably going through a lot of troubles and thankfully he didn't take anybody else out with him," Thill said.

Chris Brownson is the Director of the Counseling and Mental Health Center at UT. He said suicide is the second leading cause of death for college students.

He said it’s good therapy for students to gather and talk about what they’ve experienced.

“A lot of times people joke about suicide, but I always encourage people when a friend says something like that or a family member, to follow up. Help is available and getting them connected can save a life," Brownson said.

He said students can help each other cope with their feelings just by talking about them.

UT's Counseling and Mental Health Center is offering psychological services to those who need them.
