New updates in the missing Colorado mom case have surfaced, which may provide details to the whereabouts of Kelsey Berreth, 29. The flight instructor and mother was last seen with her one-year old-daughter on Thanksgiving Day in a Safeway in the Woodland Park, Colorado, community where she lives.

The father of the child was scheduled to meet Berreth to pick up his daughter later that day as part of their scheduled custody arrangement. Berreth reportedly texted the father on Nov. 25 as well as her employer at Doss Aviation, saying that she would be missing from work the following week. She has not been heard from since the text messages arrived.

The Daily Mail, however, has reported another clue in the case that surfaced on Nov. 25. Berreth’s phone pinged a cell tower located in Gooding Idaho at 5:13 p.m. The location is approximately 800 miles from her home in Woodland Park, according to the news outlet.

While Berreth has family in Idaho and Washington, they have not seen her and are rightfully concerned about her wellbeing. The family is posting information to a Facebook page to help find their daughter. Over 21,000 people are following the search on Facebook.

Berreth’s mother, Cheryl , reported her daughter missing on Dec. 2, a week after the two were last in touch. Cheryl lives in Idaho. She held a news conference with Miles De Young, Woodland Park police chief Monday saying, “Kelsey, we just want you home. Call us if you can, and we won’t quit looking.”

According to the Daily Mail, De Young was questioned about whether the case was considered suspicious. His responded by saying, “I have nothing to indicate other than that it is a missing persons case.”

Berreth’s daughter’s father is cooperating with investigators and the little girl remains in his custody, the news outlet reported.

Both Berreth’s home and work have been searched for clues. Investigators have not identified a suspect in the case, according to De Young. The family has also started GoFundMe page to help pay for search, investigation, and other expenses related to finding Berreth.
