(Clark County, WA) -- Authorities are looking for a vehicle of interest in connection to the Nakia Creek Fire. The Clark County Fire Marshal's Office has identified a white or light-colored Subaru that was caught on October 9th- the day the fire sparked. Officials believe two men and two women are connected to the vehicle. This comes after the Washington State Department of Natural Resources announced last week that the Nakia Creek Fire was believed to be human-caused.
