DEVELOPING STORY – Several people were killed and multiple people were injured in a shooting at Marjory Stoneman Douglas High School in Florida this afternoon, prompting a massive police response and manhunt as frightened students hid in their classrooms.

The Broward Sheriff’s Department said there were “at least 14” victims. A law enforcement source says the victims include fatalities.

The sheriff’s department tweeted after 4 p.m. that a shooter was in custody. They said the scene was still active. A male that fit the description of the suspect was seen being taken into custody.

Broward County Schools superintendent Robert Runcie confirmed there were numerous fatalities, but couldn’t confirm the number.

“It’s just a heartbreaking tragedy,” Runcie said.

Runcie said it’s possible the shooter was a former student who entered the school during dismissal. Runcie said there was no warning or threats made before the incident.

Ambulances converged on the scene as emergency workers appeared to be treating possibly wounded people on the sidewalks.

Television footage showed police in olive fatigues, with weapons drawn, entering the Marjory Stoneman Douglas High School, then dozens of children frantically running and walking quickly out. A police officer waved the students on, urging them to quickly evacuate the school.

Some students exited the building in single-file rows with hands raised overhead to show they carried no weapons. Others held onto other students as they made their way out past helmeted police in camouflage with weapons drawn.

Emergency medical personnel pulled stretchers from the backs of ambulances as police cars surrounded the parking lot. At least one person was seen being wheeled to the ambulance on a gurney.

Students at the school were being evacuated to West Glades Middle School Wednesday afternoon. The Coral Springs police department tweeted it is assisting and that the middle school was on lockdown as a precaution.

“We understand you are worried for your children,” the department said.

Student Jeiella Dodoo said a fire alarm went off around 2:30 p.m. She said the school already had a drill earlier in the day.

Then, she said she heard about six gunshots. Everyone ran, and Dodoo described a chaotic scene as students fled. She said she hurt her toe while jumping a fence. She heard from a friend that people were being loaded into ambulances.

“That’s when we knew it was really real, there was an actual shooter on campus,” Dodoo said.

Parent Caesar Figeuroa said his daughter was hiding in a closet and afraid to speak on the phone. He said they have been texting. The girl said she heard gunfire and the window blew, and she screamed and ran in the closet with her friend. She told Figeuroa she heard everyone screaming and running.

She said three students were shot in the classroom next to her. She was no longer hearing gunfire, Figeuroa said.

He said it was like a “war zone” with the police response.

“It’s the worst nightmare not hearing from my daughter for 20 minutes, it was the longest 20 minutes of my life,” Figeuroa said.

Officers asked people to avoid the area. The Coral Springs Police Department told teachers and students to remain barricaded inside until police reach them.

The White House said President Trump has been briefed on the shooting and is monitoring the situation. The White House said President Trump has been briefed on the shooting and is monitoring the situation. Mr. Trump expressed his condolences in a tweet Wednesday afternoon, adding that “no child, teacher or anyone else should ever feel unsafe in an American school.”

“All of a sudden there was a really loud noise people are crying the closet,” the student wrote to him.

The FBI said it was on the scene and assisting local law enforcement. ATF agents from the Miami Field Division are also responding to the scene.
