Investigators probe 2011 death of rural Missouri couple

SPRINGFIELD, Mo. -- Investigators are continuing to probe the 2011 deaths of a rural southwest Missouri couple, according to recently released court documents.

Donald and Helen Willingham, both 79, were killed April 25, 2011, in their home outside Springfield. Jose Huckleberry is being held on first-degree murder charges.

A recently unsealed warrant shows a woman called 911 from the Willingham home the morning the couple was killed and said a "young man" was in her house, fighting with her husband. There was an apparent struggle, the woman screamed, and the call was disconnected.

A few minutes later, a neighbor, Craig Hilburn, called 911 to say he saw someone in the driveway of the home, the warrant says. Hilburn tried to chase the man but lost sight of him, then returned to the house and found one of the bodies.
