The Lone Star College Public Information Officer, Vicki Cassidy, said the school was on "high alert and will continue the same pattern" Wednesday. The PIO also said there would not be extra security on campus.

However, security on the college campus was much more visible early Wednesday. Officers were out patrolling the campus to help ease fears as students headed back to school.

"It makes you scared to go anywhere," student Danielle Roberson said. "You are at school to get an education and better our future and we still get to school and get nervous."

Lone Star College and the four nearby Aldine schools -- Dunn Elementary, Parker Intermediate, Nimitz 9th grade campus and Nimitz High -- were on lockdown Tuesday. The lockdown was lifted about 3 p.m.

"I'm just glad nothing happened at any of the other schools and the suspect didn't make it to other schools," said Kevin Williams, who has two children who attend Dunn Elementary. "As a parent, you think, 'Go get my child, go help my child,' but you have all the police, so what else can you do?"

Town hall meeting scheduled

Harris County sheriff's deputies will hold a town hall meeting to talk with the public about the department's plan for responding to school shootings.

The meeting will be held at San Jacinto College's North Campus, 5800 Uvalde, from 6 to 8 p.m.

Garcia said the timing of the meeting was coincidental and not in direct response to the Lone Star College North campus shooting. The meeting was organized after the school shooting in Newton, Conn.

"We want people to know that our deputies are prepared, they're brave, they're courageous, they're going to run toward danger that people will run from and, in the event they might be outgunned, we got surprises for the bad guys."

Guns illegal on campus

There were more than 10,000 students on the campus at the time of the shooting, said Jed Young, a school spokesman. Lone Star College's North Harris campus sits on 200 acres and opened in 1973. It offers more than 80 programs of study.

It is illegal to carry a concealed gun on a college campus in Texas.

"The policy of the board is that it's a gun-free campus," Carpenter said. "That doesn't mean that we can observe every ... we've got 19,000 students on this campus. We don't search students that come on the campus."

According to college officials, administrators have been actively talking about how they should deal with a shooter on campus. On Tuesday morning, the college president sent faculty members a link to a video that demonstrates what to do in an active shooter situation.

College officials said an email to a link with a training video will be sent to students.
