A convicted murderer pleaded guilty to another murder charge in September in the killing of his cellmate.

Tony King, 29, of Bethany, was charged in June with second-degree murder in the death of registered sex offender, Michael Bozarth, 25.  The St. Joseph resident was found strangled in the cell the two shared at the Buchanan County Jail on June 11.

King was awaiting sentencing for the January 2012 death of his son, Jeremiah Lamm, 7, whose body was found in the charred remains of a mobile home in Harrison County.  King was found guilty last month of first-degree murder, arson, and felony child abuse.

King is scheduled to be sentenced Thursday at 4 p.m. in Buchanan County.
