SACRAMENTO . (AP) — Two state firefighters were fired Wednesday and another has resigned after an ethics investigation that stemmed from the killing of a battalion chief’s girlfriend. Thirteen other California Department of Forestry and Fire Protection employees face discipline including suspensions, demotions or reductions in pay, department spokeswoman Janet Upton told The Associated Press. Fifteen of the 16 were instructors at the department’s fire academy in Ione, 40 miles southeast of Sacramento.
