The investigation into the disappearance and presumed murder of Kelsey Berreth is reportedly focused on a landfill in Fountain, Colorado, about 40 miles from Berreth’s home in Woodland Park.

ABC News reports that a spokesperson for Midway Landfill said that investigators had been in contact about a search of the landfill, believed to be related to Berreth’s murder investigation.

The waste management facility is in Fountain Colorado, near Colorado Springs and about 40 miles south of where Berreth was last seen.

“The Colorado Bureau of Investigation contacted Waste Management of Colorado regarding a potential search at Midway Landfill and we are cooperating fully,” Waste Management spokeswoman Anne Spitza told ABC News on Wednesday.

She declined to provide further details about the landfill search, referring the news station to the District Attorney’s office, which reportedly refused a comment, as did the Colorado Bureau of Investigation.

Berreth, 29, has been missing since Thanksgiving Day. On December 21, Patrick Frazee, the father of Berreth’s 1-year-old daughter, was arrested and charged with her murder. Authorities said at a press conference announcing his arrest that they no longer believe Berreth is alive, and that a crime likely took place in her Woodland Park home on or around November 22.
