Clarksville investigators say a man admitted to beating his mother to death for drug money.
Lee Watts was arrested for murder last month.
Officers found Ethel Adamson unconscious in her home on Central Avenue, and she later died at the hospital.
During a preliminary hearing this week, detectives described interviewing Lee.
According to our news partners at The Leaf Chronicle, Lee first claimed he came home and found his mom beaten.
Investigators say he ultimately confessed to the crime and said he used the money to purchase drugs at a hotel.
