EDMOND — An Edmond man told police he used his foot to hold his 89-year-old aunt's head under water in the bathtub and later tried to make it seem like an accident, according to an affidavit filed Monday in Oklahoma County District Court.
Ronald Vincent Sparks, 47, was arrested on a murder complaint Saturday after he told detectives he killed his aunt, Edmond police said.
They have not released the woman's name pending notification of out-of-town relatives.
Officers were called about 3:20 p.m. Saturday to the residence at 1000 E Edwards St. When they arrived, they found the woman dead in the bathroom.
Sparks told officers he lived at the home with his mother and his aunt. Police said Sparks' mother was not home when the aunt died.
Neighbors said Sparks appeared to have a mental illness and always was yelling and talking to himself. Police said he wasn't seeking aid for any illness at the time of the attack.
According to the probable cause affidavit, Sparks told police he thought his mother and aunt were two of “the most evil people that he had ever met.”
He told police they were planning to kill him and they might have put something in his morning coffee.
After his mother left for work, Sparks questioned his aunt about why someone would want to kill an innocent person, and she acted like she didn't know what he was talking about, he told police.
Sparks said he filled the bathtub sometime between 9 a.m. and 1 p.m. When his aunt walked toward the bathroom, he came up behind her and put her in a “Chinese Death Lock,” according to the affidavit.
