More details are coming in about Nikolas Cruz, the 19-year-old identified as the suspect in Wednesday's shooting at a Parkland, Florida high school that killed at least 17 people.
Although Cruz tried to escape by blending in with other students evacuating the school, he was detained by authorities and arrested.
He reportedly had an AR-15-type of semi-automatic rifle and "countless magazines," according to the Broward Sheriff's Office. He was also carrying smoke grenades and a gas mask, according to Senator Bill Nelson of Florida.
Nelson said that Cruz set off the fire alarms at the school "so kids would come pouring out of the classrooms into the hall" during the shooting spree.
While investigators are still looking at his motive for the shooting, we do know that he was expelled from the Marjory Stoneman Douglas High School, where the shooting took place, for disciplinary reasons that included threatening other students.
Some students at the school said they knew that Cruz was a bit off and was into guns.
