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.
He told police he “snapped her” and choked her for a while and then put her face first into the bath water.
The woman attempted to raise her head up out of the water, but Sparks said he kept his foot on her head until she stopped moving, according to the affidavit.
He said he left her submerged in the water and left the house for a couple of hours. When he returned, he called 911.
According to the affidavit, Sparks said the dispatcher told him to get her out of the water and start CPR, but he didn't want to. He said he got her out of the water and barely pressed on her chest because he knew she was dead.
Police said Sparks told detectives he hoped they would think her death was an accident or a medical situation. He said he put one slipper on her foot to make it look like she had slipped in the bathroom. Sparks said he also threw her broken eyeglasses into the bathtub.
Officers at the scene noticed the woman had a bloody wound on the top of her left hand, and there was some blood on the side of the tub and wall. The woman also had bruises on her face.
Police said investigators concluded that there was some type of struggle in the home and arrested Sparks. He is being held in the Oklahoma County jail without bail.
