Kelsey Berreth Update: Investigators To Search Landfill For Missing Colorado Woman

Colorado authorities announced plans Thursday to search a landfill for the possible remains of a woman who went missing on Thanksgiving.

Police in Woodland Park stated that the search for Kelsey Berreth, a 29-year-old mother, could last for months and that they expect to find evidence approximately 15 feet below the landfill's surface, according to ABC News.

It is not clear as to why authorities have scheduled the search for Tuesday, but Woodland Park police have already roped off the perimeter of a quarter acre-sized patch in the 553-acre Midway Landfill.

The landfill has been an area of speculation since mid-January, according to Waste management officials, who had been informed at the time by the Colorado Bureau of Investigations about a potential search and are fully cooperating with authorities.

Berreth disappeared on Nov. 22 from Woodland Park, a city 88 miles sound of Denver. She had been seen on a surveillance video at a nearby Safeway with her 1-year-old daughter, Kaylee, and has not been seen since.

Patrick Frazee, the father of her child and her fiancee, was arrested in December and charged with Berreth's murder. He has been charged with first-degree murder, tampering with a body and other offenses, according to court documents.

Frazee was arrested after the testimony from Krystal Jean Lee Kenney, a 32-year-old Idaho woman and former nurse who was purportedly in a relationship with him.

According to an affidavit signed by Kenney, Frazee blindfolded Berreth under the guise of asking her to identify the scents of different candles in her home. While she was unable to see, Frazee attacked her with a baseball bat, killing her with a blow to her face.

After calling her over to the victim's house, Kenney then assisted Frazee in cleaning up the scene in an attempt to erase all evidence that a crime had been committed. The pair then placed the body in a black plastic bag and drove to Nash Ranch in Park County, Colorado, where they placed the bag on top of a haystack.

Two days after the alleged murder, Frazee and Kenney retrieved Berreth's remains and took them back to Frazee's residence in Florissant, Colorado, where they burned them in a water trough, along with the murder weapon and Berreth's cell phone.

Kenney, who alleges that she was not present for the murder of Berreth, has also been charged with tampering with a body.

The affidavit also suggested that the motive for the murder was over custody issues concerning Frazee and Berreth's infant daughter, who was reportedly in the house when the attack occurred, though she remained unharmed.

In addition to criminal charges, Berreth's parents Cheryl-Lee and Darrell Lynn Berreth, who have retained custody of the child, have filed a wrongful death suit against Frazee, which also alleges the murder was committed over a custody dispute.
