KIRKSVILLE, Mo. - A U.S. man accused of killing and dismembering another man, then setting fires to conceal the crime, hurled the victim's arms at witnesses shortly before he was arrested, police said.

Paul R. Potter, 49, was charged Monday with second-degree murder, arson and tampering with a motor vehicle and is being held on $1 million bond. Kevin Locke, the public defender assigned to represent Potter, did not immediately return a phone call Tuesday seeking comment.

Authorities are not releasing the victim's name until relatives have been notified, the prosecutor's office said.

Police officers responding to a call of a vehicle fire Sunday arrived at a public housing development and saw Potter "throw two objects, later identified as human arms, toward the witnesses," according to a probable cause statement.

Potter was taken into custody "and blood evidence was later collected from his hands," the statement said.

Fires had been set in two apartments. Officers and firefighters found a dismembered body with additional wounds to the face and sternum in one of the apartments. Both apartments were both strewn with blood.

Potter had taken "substantial steps to conceal the crime and divert attention away from the crime," the police statement said.

Two vehicles also had been set on fire and police said they found several knives inside and around one of the apartments.

Witnesses told police that Potter had been involved in a nearby disturbance earlier that day.
