A man accused of killing his mother plead guilty Tuesday.
Daniel Sanders plead guilty in court to voluntary manslaughter and tampering with physical evidence in a plea agreement.
The plea agreement brought the original charge of second degree murder down to voluntary manslaughter, which is a Class B felony.
Sanders admitted in court that he got in a fight with his mother before drowning her in the bath tub in August 2008.
Boone County Assistant Prosecutor Andrew Scholz said that Sander drove to the town of Englewood, which is south of Columbia, to bury the body. However, when he was on the side of the road, people kept interrupting and asking Sanders if he had car trouble and needed help.
Because of the constant interruptions, Sanders decided to drive back to Columbia.
Sanders was arrested after police pulled him over for reckless driving at Stadium and Audubon. When police went to search Sanders TM car before having it towed, they found his mother's body, Helen Sanders, in the trunk.
Officers found Helen Sanders TM body wrapped in a blanket in the trunk of the Mercury Marquis.
Autopsy results showed that Helen Sanders might have drowned.
Sanders got the maximum punishment for both charges: 15 years for voluntary manslaughter and four years for tampering with physical evidence.
