BETHANY, MO. (AP) -- A northwest Missouri man whose son was found dead in their burned-out mobile home has been charged with murder and arson.

The St. Joseph News-Press reports that 28-year-old Tony King of Bethany, was arrested and charged Friday by Harrison County authorities.

Firefighters responding to the blaze Wednesday morning found the body of King's son, 7-year-old Jeremiah Lamm, in a bedroom. The Harrison County coroner said Friday the cause of death is still being investigated.

King was being held in the Harrison County Jail on $250,000 bond. He's charged with first-degree murder, child abuse and second-degree arson.

Online court records did not list a lawyer for King, and no phone number could be found for his listed address.
