Investigators are taking a close look into the cause of a Monday morning SUV fire outside a home in Graham. It was the latest in a series of suspicious vehicle fires in Pierce County. Firefighters responded to the scene, in the 10500 block of 197th Street, at around 6:15 a.m. after receiving reports of a vehicle fire. Crews were able to extinguish the flames before they spread to a home just a few feet away. No one was injured. The location of the fire was about a mile away from another suspicious car fire last June in South Hill that spread to a nearby home, displacing the eight family members who lived there.
