Allen Scott Martin, 43, pleaded guilty to a reduced charge of voluntary manslaughter and concealing the death of another. He had been indicted by the grand jury in February on counts of murder, felony murder and concealing the death of another.
He was sentenced to 30 years -- 20 years for the voluntary manslaughter count and 10 years for concealing a death, to be served consecutively. District Attorney Joseph Campbell said his office pursued the maximum sentence for those charges.
Because a person can only be sentenced on one murder charge, the original felony murder and murder charges were combined for sentencing purposes, according to court documents.
Campbell said the discussion of a plea was relatively new to the case.
"You have no real discussion until recently," he said, adding that the attorneys always explore the possibility.
Martin was accused in the September 2009 death of his 55-year-old roommate, Roy David Owens.
Owens' body was discovered behind a trash bin at Bartow Motel, 803 Joe Frank Harris Parkway, Cartersville.
According to the indictment, Owens died after being struck "in the head and face area with unknown solid objects similar to hands, feet and footwear."
In September 2009, Cartersville Police Department Capt. Frank Cline said that evidence at the scene indicated Martin "moved [Owens] from where he died and hid him in the woods" and "cleaned up the room a lot."
