Seventeen people were killed in a shooting at a Florida high school, Broward County Sheriff Scott Israel announced Wednesday.
The shooting took place at Marjory Stoneman Douglas High School in Parkland, and the shooter is in custody.
Israel said the victims included both students and adults. He identified the suspect as Nikolas Cruz, 19, and said he was a former student of the school who got expelled for disciplinary reasons.
Florida Senator Bill Nelson told CNN, “It’s a bad day for Florida and for the country.”
Nelson added, “How many of these have we had? Are we coming to expect these mass shootings to be a routine kind of matters and after every one we say enough is enough? And then it continues to happen.”
Coral Springs police also announced in a tweet that the school perimeter has been locked down.
According to an unidentified student who spoke with WSVN, the school had a fire drill earlier in the day, and when the shooting occurred, people thought it was another drill.
“We already had a drill today so we thought it was just another drill,” the student said. He added, “We heard a pop and then from the other side of the school, we saw the whole school running out.”
