Don McRoberts, 53, was found dead inside his West Cherry Street home in Troy, Missouri, in December 2011 after a fire that was later ruled arson. Firefighters discovered his body amid the charred remains, and investigators determined he had suffered a gunshot wound before the house was set ablaze.

Authorities say the killing grew out of a bitter real estate dispute. McRoberts had bought a house from Michael and Jennifer Hall at a foreclosure sale and allowed them to remain as tenants under an agreement to buy it back. When the Halls fell behind on payments McRoberts evicted them; investigators say that eviction, combined with McRoberts acting as a witness against Michael Hall in an unrelated fraud case, provided the motive.

Investigators allege Michael Hall solicited his brother, Allen Hall, and Allen’s girlfriend, Viola Jody Helm, to kill McRoberts. Allen Hall is accused of shooting McRoberts in the head and, together with Helm, setting the fire. Does anyone have information about McRoberts, the property on West Cherry Street, or contacts who might help clarify what happened that day?
