WELCH - An 81-year-old Welch woman who died in August was beaten so severely she had a broken nose and several teeth were chipped or knocked out, according to the final autopsy report.
Michael Joe Rice, 48, is charged with first-degree murder and rape in the death of his adoptive mother, Ruth Rice.
Michael Rice had been drinking the night of the killing and told police he killed Ruth Rice, law enforcement officers said.
The state medical examiner reported Ruth Rice died from blunt head trauma. Injuries, according to the report, included a five-inch bruise from her right upper cheek to her right ear and fractures in her nasal bones and facial bones. The victim had bruises on her back, chest, abdomen and both arms and legs.
There was also evidence of a sexual assault, the autopsy report noted.
Michael Rice initially reported the Aug. 4 attack to law enforcement officers. He later told Oklahoma State Bureau of Investigation agents he tackled his mother as she walked to the back door of her home, then struck her in the head several times and sexually assaulted her, according to a probable cause affidavit.
Ruth Rice's body was found near the back door of her home with blood on her face, body and the floor around her. A black nylon rope with keys attached was found around her neck, the autopsy report states.
Bob Horn, Ruth Rice's neighbor for 25 years, said he wasn't aware why Ruth Rice would carry her keys around her neck.
"Michael didn't work, and his mom supported him," Horn said. "She threatened over the years to cut him off (financially); she finally did it."
Michael Rice has a criminal history of drunken driving, supplying beer to a minor and reckless driving. He remains in the Craig County jail with no bail and is scheduled to return to court Jan. 9 for a preliminary hearing, according to court records.
The state has not decided whether to seek the death penalty against Michael Rice, said Bryce Lair, Craig County assistant district attorney.
Efforts to reach family members of the victim were unsuccessful.
