Stillwater Man Arrested on Murder Charge

A missing person case turns into a homicide investigation for the OSBI.

The OSBI says 29-year-old Chelsey Chaffin moved into a co-worker's house two weeks ago in Stillwater and was never heard from again. That co-worker, 54-year-old Earl Oswalt, has now been arrested for her murder. The OSBI says Oswalt killed Chaffin and dumped her body off a bridge into the Cimarron River. Her body still has not been found. Oswalt is a registered sex offender. He spent 20 years in prison on a rape conviction and was paroled in 2017.
