SEE IT: Police release surveillance footage showing missing Colorado mom just before she vanished on Thanksgiving

Authorities in Colorado have released video footage of a now-missing young woman, taken at a grocery store the day she was last seen.

Kelsey Berreth, 29, of Woodland Park vanished on November 22, Thanksgiving Day, after being spotted in a Safeway supermarket with her 1-year-old daughter. Berreth then reportedly met with her fiancé Patrick Frazee, who does not live with her, to hand off her daughter to the baby’s father.

Berreth’s mother reported her missing 10 days later. On November 25, text messages from her phone were sent to her employer, Doss Aviation, informing the company that she would be taking time off, and to Frazee. The contents of the message to her fiancé is not known.

Sometime after her disappearance, Berreth’s cell phone pinged hundreds of miles away in Idaho, though authorities indicated they are not certain she was with her phone at the time.

On Tuesday, Woodland Park police released surveillance video of Berreth at the Safeway supermarket, with her daughter in a baby carrier. The footage, which was obtained and published by the Denver Channel, represents the last known sighting of Berreth.

Berreth is white with light brown hair, 5’3” tall, and weighs 110 pounds.

Anyone with information about Berreth’s whereabouts is urged to call the Woodland Park Police Department at (719) 687-9262.
