— A man arrested in the shooting death of a prostitute told investigators he planned to use a knife or strangle her and have sex with her, but he had to use a gun instead because she arrived with two other people, court records state.

Timothy Earl Slawson, 21, is charged with first-degree murder in the shooting death of Mindy Dawn Carder, 33, of Oklahoma City. Carder's partially clothed body was found Friday at a Logan County dead-end road in the 9900 block of S Bryant Ave.

Slawson said he had sex with her after she died, but “only for a short time because she was dead and it just wasn't right,” according to an affidavit filed in Logan County District Court.

The document attached to the charge states Slawson used a cellphone Thursday to arrange a meeting with a prostitute he found on a website. He planned to use a knife or strangle her when she arrived, the affidavit states.
