A young Colorado mother who vanished on Thanksgiving was out of contact with family and friends for 10 days before she was reported missing.

As CrimeOnline previously reported, Kelsey Berreth, 29, was last seen at a Safeway supermarket near her Woodland Park home on Thanksgiving Day, before she reportedly met with her fiancé Patrick Frazee so he could pick up their 1-year-old daughter.

According to CBS News, text messages from her cell phone number were sent to her employer, Doss Aviation, and Frazee three days later. That same day, her cell phone reportedly pinged in Gooding, Idaho, several hundred miles from her home. As CrimeOnline previously reported, authorities indicated that are not sure if Berreth was with her phone at the time.

The text message to Berreth’s employer reportedly said that she would be taking some time off from work. The contents of the message sent to Frazee is not yet known.

But it would be another week before Berreth’s mother filed a missing persons report, 10 days after her daughter was last seen. Berreth’s fiancé did not appear at a police news conference on Monday regarding Berreth’s disappearance.

Woodland Park Police Chief Miles De Young told CBS News that authorities have not yet identified any suspects in Berreth’s disappearance, though it remains unclear why Frazee did not contact police.

“We are treating Kelsey’s disappearance as a missing person’s case at this time. We have not identified anyone as a suspect, and are asking the public for any information that might help us find her,” De Young reportedly said.

The police chief also said that Frazee is cooperating with police and that there is no evidence of previous domestic violence involving the engaged pair.

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.
