Chelsey Nicole Chaffin was 29 when she disappeared from Stillwater, Oklahoma. The last known contact with her was on May 25, 2019; she had moved into a coworker’s home a day earlier after a disagreement with her fiancé and left her dog behind. Attention soon focused on that coworker, Earl Oswalt Jr., a registered sex offender who initially said Chelsey left with an unknown man.

Investigators say Oswalt confessed that in the early morning of May 26 he grabbed Chelsey by the throat and later punched her in the face, an assault that led to her death. Accounts vary on what happened next, but her body was reportedly wrapped in a blanket and disposed of. Oswalt later told authorities he and his fiancée threw the body from a bridge into the Cimarron River; his fiancée said she was not present at the killing but later saw Chelsey’s body at the house and helped dispose of it. Searches of the Cimarron River have not recovered Chelsey’s body.

Earl Oswalt Jr. was arrested in June 2019. Did anyone in Stillwater have contact with Chelsey in late May 2019 or see her after May 25?
