BROWARD COUNTY, Fla. -- More than a dozen survivors of the Marjory Stoneman Douglas High School shooting filed a federal civil rights lawsuit Wednesday.

The civil lawsuit was filed on behalf of 15 survivors of the Feb. 14 mass shooting at the school in Parkland, Fla., that left 17 people dead.

"All plaintiffs were present at Marjory Stoneman Douglas High School during the shooting and suffered harm during the shooting in the form of, at least, severe psychological injury and trauma," says the lawsuit, filed in U.S. District Court in South Florida.

The defendants named in the suit include Broward County; Sheriff Scott Israel; former Deputy Scot Peterson; Andrew Medina, a school guard; Jan Jordan, a Broward captain who was commander of the shooting scene; three John Does; and Broward Schools Superintendent Robert Runcie.

The Parkland survivors allege that Runcie and Israel were both "well aware of the potential danger" of the alleged gunman, a former student.

It also says a neighbor called the Broward Sheriff's Office to report that before he was expelled from the school, the alleged gunman made an Instagram post threatening to shoot up the school, and no action was taken by the defendants. It said the Sheriff's Office had received "dozens" of calls from 2008 to 2017 warning them about the gunman.

Finally, the lawsuit alleges that the county failed to adequately train officers on proper procedures for investigation, harming the plaintiffs.

The suit seeks compensatory and punitive damages determined by a jury.

The plaintiffs are being represented by the same attorneys who filed a similar complaint last month on behalf of Pulse nightclub survivors.
