Shots fired at Houston-area community college, police say An aerial view of the scene at Lone Star College's North Harris campus in Houston on Tuesday. Sheriff's deputies were responding to reports that shots were fired at a Houston-area community college with multiple people wounded. NBC station KPRC-TV reported that police had one person in custody and were searching a sub-division near the North Harris campus of Lone Star College to determine if another person who fled the scene could be a possible suspect. Live aerial video taken by the station showed emergency crews moving two people on stretchers into ambulances. Dozens of police vehicles were visible. Police officers in SWAT gear were shown on the video entering buildings on the campus. A law enforcement source told NBC that three people were shot and one person possibly suffered a heart attack. At least one person has been detained at the college, deputy constables told KPRC, but they did not say if that person was suspected of shooting anyone. Deputies were also searching a sub-division for another person who fled the scene. It has not been confirmed if that person is a suspect in the shooting. Witness Amanda Vasquez told KPRC she was in English class when she heard shots fired, apparently in the hallway. She said she got under her desk, while other student ran out of the classroom. Jed Young, a spokesman for the college system, told The Associated Place that a "shelter-in-place order" was issued at the college due to reports of a shooter on campus. Students, faculty and staff were advised by the college website to take immediate shelter where they were. The school later said it was on lockdown. Harris County sheriff's deputies told KPRC-TV that the shooting was reported shortly after noon CT at the North Harris campus.
