The fiancé of a young mother who vanished on Thanksgiving Day in Colorado has released a statement through his attorney.

KOAA News 5 reports that Patrick Frazee, the fiancé of Kelsey Berreth, gave the news station a statement regarding Frazee’s involvement in the investigation.

As CrimeOnline previously reported, Berreth, 29, went missing on November 22, the same day she was spotted on surveillance camera at a Safeway supermarket before meeting with Frazee to hand off their one-year-old daughter.

Berreth has not been seen since, though both Frazee and Berreth’s employer, Doss Aviation, received text messages from her phone on November 25. The message to her employer reportedly said that she would be taking some time off. The contents of the message sent to Frazee is not known.

That same day, Berreth’s cell phone pinged several hundred miles away in Idaho, but authorities have said it is not certain that she was with her phone at the time.

Berreth’s family and friends did not contact police about her disappearance until 10 days after she disappeared, when her mother reported her missing.

In a news conference on Monday, Berreth’s mother pleaded for her safe return, and Frazee was not in attendance.

KOAA News 5 reports that Frazee’s attorney Jeremy Loew said that Frazee is cooperating with investigators, and has provided law enforcement with his cell phone, DNA and some photographs.

The attorney reportedly said that Frazee was unaware of the press conference until an hour before it began, and that he would have attended if he had adequate notice.

According to the report, Berreth had not previously requested time off before the November 25 text to her employer. Doss Aviation reportedly said that no planes were missing, and that Berreth is not believed to have flown to Idaho.

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.
