POTTSBORO, TX -- The daughter of an elderly Pottsboro woman who was beaten to death has been indicted for the murder of her mother.
Last month, News 12 reported that 53-year-old, Shelia Mae Wolfe, was arrested for the murder of her mother, Marlene Cannon.
Cannon was found brutally beaten in her Pottsboro home and later died from her injuries.
According to an affidavit, Shelia Mae Wolfe, brutally beat her mother, Marlene Cannon, with a sledgehammer back in December of 2013.
Grayson County District Attorney, Joe Brown, says money may have been the reason.
"She thought her mom was going to outlive her and there was an inheritance that she wasn't going to get," Brown said.
The affidavit states Grayson County Sheriff's deputies found Cannon unconscious and lying in her bed, covered in blood.
She was flown to a hospital in Plano, where she later died from her injuries.
Brown says Wolfe lived with Cannon in the Pottsboro home and was there when deputies arrived on scene, the night of the assault.
It states a witness told investigators on that night, she saw Wolfe go into Cannon's bedroom and began screaming.
The witness said she observed Wolfe straddling Cannon's body.
Brown says Wolfe had already gotten rid of the murder weapon by the time deputies arrived.
"She used a sledgehammer while her mother was in bed and then threw a sledgehammer in a pond," Brown said.
Wolfe was arrested last month after authorities got a call from her.
She was at a nearby pond where the affidavit states she admitted to throwing the sledgehammer in.
Investigators also spoke to other people who know Wolfe and say she had a history of abusing her mother and Cannon was afraid of her.
"She had some depression and mental instability that led her probably to belief that she needed to kill her mom," Brown said.
Wolfe remains behind bars with a bond set at $1,000,000.
