This morning around 11:25 Company 5 was alerted to assist Police with assisting a person over a hillside. C-50 immediately requested Rescue 4 to be added to the assignment. Medic 59 had contacted the patient and began an assessment while Crews from Engine 51 and R-4 arrived on scene and began rigging a lowering/hauling system. Crews were able to secure the patient and extricate him up the hillside in approximately 20 minutes. Medic 59 transported the patient to the hospital for possible hypothermia.
