Law-enforcement sources reportedly identified Nikolas Cruz, 19, as the suspect in the Marjory Stoneman Douglas High School shooting.
Law-enforcement officials have begun releasing details about the suspect in Wednesday’s high-school shooting that claimed the lives of at least 17 people and injured 14.
Nikolas Cruz, a 19-year-old who had been expelled from Marjory Stoneman Douglas High School, where the shooting took place, was taken into custody by the police, the Broward County Sheriff's Office confirmed.
Jim Gard, a teacher at the school who taught Cruz, said that he was told Cruz "wasn't allowed on campus with a backpack on him" and that Cruz had threatened fellow students, the Miami Herald reported.
Robert Runcie, the Broward Schools superintendent, said that while there "potentially could have been signs" the shooting would happen, officials "received no warnings," the Herald reported.
A student who attended the same alternative high school as Cruz after Cruz’s expulsion said Cruz was known to have flaunted pictures of firearms on his phone.
"He shot guns because he felt that it gave him an exhilarating feeling," the student said on Miami’s WSVN-7 News. "He showed me personally through his phone."
"I didn't want to cause any conflict with him because that's the impression he gave off," the student added.
The student also said he knew as of two years ago that Cruz had guns at his home.
"It surprises me the fact that this is going on today, but it doesn't shock me that it was him," the student said. "It was an eye-opener."
The school enrolled 3,208 students grades nine to 12, according to the Sun-Sentinel.
