Lone Star College near Houston was locked down Tuesday after an on-campus altercation led to a shooting that injured three people, including the only shooter.
Carlton Berry, 22, is charged with aggravated assault in the shooting, Harris County Sheriff's Office spokesman Alan Bernstein said.
Berry remains hospitalized from wounds sustained in the incident, Bernstein said.
Lone Star College said the shooting took place at about 12:30 p.m. at the community college's North Harris campus, which is located at 2700 W. W. Thorne Drive, west of Bush Intercontinental Airport.
Students at the school told KPRC-TV in Houston that two or three people were involved in a dispute inside the library.
The sheriff's office later said that only one gun was recovered from the scene and that there was no second gunman. One person shot two other people, including a school maintenance worker, and then apparently shot himself, authorities said.
School officials said Tuesday afternoon that the shooting took place outside, between buildings.
Maj. Armondo Tello, the acting chief of the sheriff's department, said no arrests have been made. Two people who are hospitalized are classified as persons of interest, he said.
The school maintenance worker was struck in the calf and was stable at a hospital, Tello said.
Bernstein said the identity of the worker and the other person injured in the shooting were not available.
Tello earlier said the other person injured in the shooting was involved in the initial altercation. He would not say if the shooting was gang-related.
A woman who sustained an apparent panic attack was also transported to an area hospital.
Earlier in the afternoon, the school posted messages on its website that said the campus was locked down and that students were advised to shelter in place. That message was followed by another that said the campus was being evacuated. Eventually, the campus was closed for the remainder of the day. Richard Carpenter, with the college, said the campus would reopen to students on Wednesday.
Four nearby schools in the Aldine Independent School District were locked down as a precaution.
According to its website, the Lone Star College System is the largest institution of higher learning in Houston and is the fastest-growing community college system in Texas. The school has approximately 90,000 students spread over more than a dozen campuses. School officials said 19,000 students are enrolled at the North Harris campus.
