Matthew Walker, a 17-year-old junior
told WFOR-TV, “He was going class to class just shooting at random kids. Everything he posts (on social media) is about weapons. It’s sick.”
A student who knows Cruz told the news station, “He always had guns on him and stuff like that. He was a little bit of a troubled kid.”
Police received a tip that the suspect was possibly watching videos on Youtube about how to make bombs, according to police scanner transmissions. Police were searching the building as a precaution after learning about that information, but it is not known if there were any bombs left in the school.
