Kelsey Berreth

The investigation after a Colorado mother vanished on Thanksgiving

Flight instructor and mother Kelsey Berreth disappeared from Woodland Park, Colorado, on Thanksgiving in 2018. Investigators examined her fiancé Patrick Frazee’s account and evidence supplied by Krystal Lee, who testified about the killing and its concealment. A jury convicted Frazee in 2019 of murder and related offenses. He received life without parole plus additional years. Colorado’s appeals court upheld the conviction in December 2022, a ruling reported by local newsrooms the following month.
