Details of Disappearance

Chaffin was last seen in Stillwater, Oklahoma on May 25, 2019. She and her fiance had had a fight on May 24, she moved out of their home and into a residence near east 32nd Avenue and Fairgrounds Road a day earlier; the house was owned by Earl Oswalt Jr., who worked with Chaffin at a tile company, Armstrong Industries. After her disappearance, Oswalt claimed she left with an unknown man, leaving her dog behind.

A photo of Oswalt is posted with this case summary. In June, he was arrested and charged with Chaffin's murder. He is a registered sex offender who had been paroled in 2017 after serving twenty years of a sixty-year sentence for rape in the first degree. Chaffin's fiance stated he believed Oswalt and Chaffin were lovers and that she did not know about his background.

Oswalt confessed that he'd killed Chaffin during the early morning hours of May 26. He said he, Chaffin and another resident of the house had been drinking, and at some point Chaffin got angry and threatened the roommate. Oswalt then grabbed her from behind by the throat, and she hit  him in the head and walked out of the room. When she came back she was naked. He punched her in the face, and he couldn't remember what else he did to her, but she died. He and the roommate then wrapped Chaffin's nude body in a red blanket and dumped it off a bridge into the Cimarron River at 1:00 a.m. the next day.

The roommate whom Oswalt said had helped dispose of the body stated she wasn't there at the time of Chaffin's murder. She said Oswalt picked her up, and he was covered in blood and his right hand was extremely swollen. When they went to the house, Chaffin was naked and lying on her back, bleeding from the nose, and she had marks on her neck.

Oswalt is awaiting trial for second-degree murder. Chaffin's body has never been found, but foul play is suspected due to the circumstances involved.
