They said the message indicated that missing mom Kelsey Berreth planned to be away the week after Thanksgiving.
Berreth, who has a 1-year-old daughter, has still not returned home.
Detectives said the text was sent to Berreth’s employer at Doss Aviation, a company that provides flight training for the U.S. military and international armed services.
Another text message was sent to Berreth’s fiancé, Patrick Frazee, though investigators did not disclose what it said.
According to the Dail Mail, Woodland Park Police Chief Miles De Young said at a news conference that Frazee was cooperating with the investigation.
Frazee reportedly told detectives that the last time he saw Berreth was on Thanksgiving Day when she gave him their baby daughter.
Last Known Location
Family members have been pushing for an expanded search for Berreth, as officials urged her to make it clear if she’s not in danger and just doesn’t want to be in contact with her family.
Berreth was last seen on Thanksgiving in several places, including the Safeway in the city of Woodland Park. The woman’s mother reported her disappearance on Dec. 2, which is 10 days after she was last seen.
The last location her cellphone pinged was nearly 700 miles away from her home.
“Kelsey’s phone gave a location near Gooding, Idaho, on November 25th at 5:13 p.m.,” Woodland Park Police Chief Miles De Young said, according to the report.
The ping could mean different things.
“It makes us wonder what she’s doing up there, or what the phone is, potentially, because she may not be there,” Cmdr. Chris Adams of the Woodland Park Police Department told ABC.
Some officials believe she may have vanished out of choice but want to hear directly from her to ascertain if that is the case.
“If she’s out there and doesn’t want to be contacted, just let us know that she’s safe and we’ll let her family know,” Adams told CBS on Dec. 9. The department planned a press conference for Dec. 10 but the details weren’t immediately clear. Family members said they would be posting “further details” after the press conference.
“Please be patient with us. We are all very tired and doing our best,” the family said on the “Help Find Kelsey Berreth” Facebook page.
On Dec. 8, the department shared a “missing person” poster with two photographs of Berreth and asked members of the public to contact them with any information regarding her whereabouts.
The FBI is assisting with the investigation.
‘Did Not Pack’
Her brother-in-law held a vigil for Berreth in Washington state, where he urged anyone who sees her to speak up.
“If they see her anywhere, please, please, please, please say something,” Kindle said. He later traveled to Colorado and said from all appearances that Berreth’s departure was spur of the moment.
“After arriving at Kelsey’s house last night and combing through her things, we know 1 thing is certain. Kelsey did not pack to go anywhere. All luggage is here. Her purse is all that seems to have gone,” he wrote in a Facebook post. Both of her cars are also still in Colorado.
The young mother is a flight instructor.
She’s described as a white female with brown hair and green eyes, standing 5 feet, 3 inches tall and weighs 110 pounds.
