(Yacolt, WA) -- A Clark County woman is facing arson charges for allegedly setting fire to her own home. Police arrested 46-year-old Angie Ingram yesterday at her house in Yacolt. Authorities say firefighters responded to the home around 5 p.m. to put out a fire in a detached shop on the property. Ingram then allegedly came out of her home and asked if the firefighters were going to put out the fire inside her home as well. A deputy peered through a window and saw a fire and smoke inside. Authorities say Ingram admitted to starting the fires, but they're still trying to figure out why.
