At 19:39hrs units were dispatched to the 2700 block of Main St. for the reported MVA. Finding nothing in the area Truck 22 stopped to check with SPD units in the Stafford PD parking lot to find the incident was actually a double shooting (having occurred elsewhere) and not a MVA. With 1-critical patient with multiple GSW’s SFD personnel and Medic 604 quickly packaged and transported to the TMC while SFD personnel treated the 2nd patient until the arrival of Medic 603 who then also rapidly packaged and transported. Following completion of assignments all units returned to service. Another of the 20-runs responded to this day.
