House Speaker Paul Ryan, R-Wis., called the shooting at a high school in Parkland, Fla., Wednesday afternoon an “unspeakable tragedy” that was a product of "true evil.”

“This is an unspeakable tragedy. It is nothing short of true evil to attack innocent children,” Ryan said in a statement.

“While we now wait to learn more, we are so grateful to law enforcement and all those who brought this horror to an end,” Ryan said. “Let us all keep the victims in our hearts. A long night lies ahead for many families. Right now, the whole country is standing with the Parkland community."

At least 14 people were injured in the shooting at Marjory Stoneman Douglas High School, and multiple people killed, according to police.

Police said the shooter, who they said is approximately 19-years-old and a former student, was found alive in Coral Springs, Fla., by a Coconut Creek Police officer and taken into custody.

Multiple outlets identified the shooter as Nicolas Cruz.

Broward County sheriff Scott Israel described the shooting as “catastrophic.”
