17 killed in shooting at high school in Parkland, Florida, authorities say

At least 17 people were dead after a 19-year-old man opened fire at Marjory Stoneman Douglas High School in Parkland, Florida, on Wednesday afternoon, officials said.

Fourteen others were wounded, five of whom had life-threatening injuries Wednesday night, hospital officials said. Authorities said the suspect, identified as Nikolas Cruz, concealed himself in the fleeing crowd and was arrested in nearby Coral Springs. He was treated for "labored breathing" as a precaution but was released from the hospital, they said.

"You come to the conclusion this is just absolutely pure evil," Florida Gov. Rick Scott, his hands clutched over his chest, said Wednesday night.

Little was known about Cruz on Wednesday night. Broward County schools Superintendent Robert Runcie said he had recently been expelled from Douglas for disciplinary reasons and was currently enrolled in another school in the district. The general store chain Dollar Tree confirmed that Cruz worked at its Parkland store and said it was fully cooperating with investigators.

Broward County Sheriff Scott Israel, who told reporters Wednesday night that the son of one of his deputies was among the injured, said Cruz was believed to have been armed with a AR-15-style semiautomatic rifle and multiple magazines. Israel said it was unclear whether he had any other weapons.
The gunfire began outside the school and continued inside, where 12 of the victims were killed, Israel said. All of those victims have been identified, he said, but no identities will be made public until the families of all of those affected have been notified.

Federal and local authorities told NBC News that there was no indication that the gunman had an accomplice or accomplices.
