Text messages were sent from missing Colorado mother's phone to employer, fiancé after she vanished, authorities say

A pair of text messages were sent from a missing Colorado mother's phone after she disappeared, authorities said Monday.

Kelsey Berreth, 29, vanished after being seen with her 1-year-old daughter in a Woodland Park supermarket on Thanksgiving Day. She was reported missing by her mother, but not until Dec. 2.

Police Chief Miles De Young said during a press conference on Monday that Berreth's employer received a text from her phone on Nov. 25, three days after Thanksgiving. The message informed the employer that Berreth would not be in the following week.

A text message was also sent from the phone to fiancé Patrick Frazee on the same day, according to the police chief. Frazee said he has not seen Berreth since he picked up their child from her at the market on Thanksgiving.

Investigators say her cell phone pinged 600 miles away in Idaho on the same day the text messages were sent.

"She's not the kind that runs off," mom Cheryl Berreth said during the press conference. "This is completely out of character. She's reliable, considerate, and honest. Kelsey, we just want you home. We won't quit looking."

Kelsey Berreth works as a flight instructor, but investigators say there is no evidence she used a plane to leave the area.

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

Anyone with information on her whereabouts should contact the police at (719) 687-9262.
