A Houston-area community college went into lockdown Thursday, but police said there is no sign of a shooter or causalities. Harris County Sheriff Ed Gonzalez says officers from several law enforcement agencies were combing Lone Star College's large Kingwood campus but have found no shooter. No injuries have been reported. The college issued a warning to go to the nearest room and lock the door around 1:40 p.m. Gonzalez says the report of a possible shooter came from “3rd party caller.” He says police are in the process of escorting people on campus to a staging area.
