PARKLAND: A law enforcement official says the former student suspected of killing at least 17 people at a South Florida high school posted highly disturbing material on social media before the shooting rampage.
Broward County Sheriff Scott Israel said Wednesday the 19-year-old suspect, Nikolas Cruz, had been expelled from Marjory Stoneman Douglas High School for unspecified disciplinary reasons.
Israel says investigators are dissecting the suspect's social media posts and found material that is "very, very disturbing." He didn't elaborate.
An ex-schoolmate recalled Cruz posting on Instagram about killing animals and said he talked of doing target practice in his backyard with a pellet gun.
A school superintendent, Robert Runcie, told reporters he didn't know of any concerns raised about Cruz.
A student who escaped the deadly shooting at a Florida high school says he knew the suspect when he attended the school, describing him as a "weird kid" and something of a "loner."
Authorities said 19-year-old Nikolas Cruz is in custody after the attack Wednesday that claimed 17 lives at Marjory Stoneman Douglas High School in Parkland. Officials say Cruz was a former student, having been expelled from the school.
Student Daniel Huerfano told The Associated Press he remembers seeing Cruz walking around the school with his lunch bag, adding, "He was that weird kid that you see ... like a loner."
