PORTERVILLE, Calif. (AP) – Police have arrested two 13-year-old boys suspected of starting a fire at a California public library that killed at least one firefighter. Porterville Police Chief Eric Kroutil said Wednesday the two teenagers were arrested in the Tuesday blaze that left a 35-year-old firefighter dead. Another firefighter is missing. Kroutil says they face arson and manslaughter charges. A city librarian says staff called 911 when they noticed flames in the children’s section of the library. More than 50 city, county and state firefighters battled the blaze for hours in Porterville. The library was built in 1953 and did not have sprinklers.
