In a case filed by current and former students who said they suffered psychological injuries, a federal appeals court is considering constitutional arguments about whether Broward County officials had a “custodial” duty to protect students from the 2018 mass shooting at Marjory Stoneman Douglas High School.

The case went to the U.S. Court of Appeals for the Eleventh Circuit after a federal district judge in December 2018 sided with a series of defendants, including Broward County, Superintendent of Schools Robert Runcie, former Sheriff Scott Israel and former school-resource officer Scot Peterson, and dismissed the case.
