KLAMATH RIVER, Calif. (AP) – The daughter of a 76-year-old man killed last month when California’s deadliest wildfire so far this year swept through a remote town has sued a public utility, alleging its electrical equipment sparked the blaze. The lawsuit filed Monday on behalf of Theresa Cogan claims the McKinney Fire started when sparks from PacifiCorp’s equipment contacted dry vegetation July 29 in Siskyou County near the Oregon border. Four residents of the tiny community of Klamath River were killed. State fire officials haven’t yet determined the cause of blaze. PacifiCorp said it doesn’t comment on pending litigation.
