A nursing home fire that killed one person and injured several others in Ohio was caused by "a clandestine methamphetamine laboratory" in one of the facility’s rooms, a fire official said Monday. Ashtabula, Ohio, Fire Department Chief Ron Pristera made the statement in a news release Monday, hours after a Sunday-night blaze hit the Park Haven Home in the town some 60 miles northeast of Cleveland. Pristera’s statement did not elaborate on what led to the conclusion that a meth lab was the cause of the fire, but photos distributed by the fire department showed scorched walls and a blackened table with remnants of an unidentified object on it.
