KINGMAN - A possible Kingman murder case remains unsolved nearly four years later.
Matthew A. McCalman, 42, of Bullhead City accepted a plea agreement Thursday morning and pleaded guilty to second-degree burglary. He could face between one to almost four years in prison or probation.
McCalaman broke into the Kingman home of Carolyn Dubois in 2005 and took several items. McCalaman was also charged with the theft of Dubois' vehicle and her credit card. Those charges were dismissed as part of the plea agreement.
Dubois was missing after the burglary was discovered and has never been found. Investigators believe Dubois may have been murdered and her body left in Nevada, but they have no evidence to prove it.
McCalman is already serving a 16-year sentence for the second-degree murder of Douglas Gardner, 51, in 2007. McCalman beat Gardner to death in Heritage Park in Bullhead City.
