Parkland Tragedy: Comprehensive Timeline

The NBC 6 Investigators combined police radio, 911 calls, witness statements, a sheriff’s animation and Scot Peterson’s Today Show interview into a second-by-second account of the crucial minutes of February 14, 2018. See and hear for yourself where Peterson was and what he and others were doing and saying as a killer stalked the hallways of the 1200 Building at Marjory Stoneman Douglas High.
