On the evening of February 8, 2012, 33-year-old Medic Weissman was gravely injured from a fall from the overpass on I-395, as it crosses Four Mile Run. At the location of the incident, the highway crosses the creek via elevated spans; some of the spans are separated from one another; some are not. At the location where Joshua Weissman fell, the northbound span is separated from the High Occupancy Vehicle (HOV) lanes.
Medic Weissman was working as a member of Medic 206. Joshua was riding in the position of the aide and would have been considered in-charge. Medic 206 was responding to a report of a vehicle fire on southbound I-395 between Seminary Road and Duke Street. It was also reported that a person may possibly be inside the burning vehicle. Medic 206 was responding with other units from the Alexandria Fire Department. The units responding to this reported vehicle fire announced not finding that vehicle fire at the dispatched location.
