Bullhead City police are seeking a man suspected of arson and aggravated assault. Trevor Bradford Maestre, 28, is wanted in connection with a reported attack Wednesday on his girlfriend, police spokeswoman Emily Fromelt said. Emergency crews were called to the 400 block of Malibu Drive for a report of a structure fire. After investigation and interviews, Fromelt said, detectives learned that Maestre allegedly held a knife to the woman’s neck and threatened to kill her. He then allegedly lit a fire in the homeowner’s bedroom and hit a man in the head with a baseball bat. The man was being treated at Western Arizona Regional Medical Center; no information on the extent of his injuries was available Wednesday.
