An Okanogan County assistant fire chief who suffered burns to more than half of his body died from his injuries on Wednesday. Assistant Chief Christian Johnson was airlifted to Harborview Medical Center in Seattle nearly a month ago after suffering severe burns while fighting the Spring Coulee Fire south of Okanogan, Washington. Johnson was in a truck with another firefighter when flames overtook them. The other firefighter outran the fire, but came back, treated Johnson and called for help. The fire started on Sept. 1 near B&O Road North between Fletcher Loop and Spring Coulee roads. It spread to the north and burned about 150 acres before being contained a short time later. Johnson suffered second and third-degree burns on over 60% of his body. He was placed in a medically-induced coma while doctors tried to stabilize him.
