Doniphan man pleads guilty to killing 4

DONIPHAN, Mo. -- A 47-year-old Southeast Missouri man has pleaded guilty to killing two elderly couples whose bodies were found in their burned-out homes two years ago.

David Youngblood, of Doniphan, was charged with murder in the June 2010 deaths of his aunt and uncle, 80-year-old Irene and 77-year-old Loyd Piatt. He was also charged with killing 81-year-old Edgar Atkinson and 69-year-old Bonnie Chase, who were found dead three weeks later in their burned-out home in Current View.

KFVS12 reported Youngblood pleaded guilty Monday. He was sentenced to four consecutive life terms in prison.

Youngblood's wife and daughter also are facing charges in the Chase-Atkinson deaths. A fourth suspect in those killings, Keith Boyles, waived arraignment Monday and is to appear in court Aug. 20.
