Texas college shooting
According to CNN, a fourth victim suffered a heart attack during the incident.
It's unclear if the suspected shooters were students at the school.
The danger on campus, according to the spokesman, had been "mitigated," police told him. Four nearby colleges were placed on precautionary lockdown.
An alert posted on the school's website shortly before 1 p.m. warned students to take shelter.
"LSC-North Harris is locked down," the alert read. "Students, faculty and staff are advised to take immediate shelter where you are. Do not enter the campus until notified further."
Aerial footage showed SWAT team members evacuating students several buildings on the campus in North Harris County near Houston as ATF, FBI and local police searched a wooded area.
In interviews with local media outlets, students described a chaotic scene. A female student told KTRK-TV heard five shots fired in an area between the library and the cafeteria. Other students say they heard gunshots when they were in cafeteria.
"I was just sitting in my room academic building, room 163 when I heard gun shots," Twitter user @Amandaplease223 wrote. "Rapid shots. In the hallway."
The Lone Star College System has a total enrollment of more than 90,000 students across six campuses, according to its website.
The shooting comes a little more than five weeks after 26 people--including 20 children--were killed after a gunman opened fire at Sandy Hook Elementary School in Newtown, Conn., sparking a national debate on gun control.
