Civil servants in Colorado have started looking for a waste processing plant at just over 40 miles southeast of the home of the missing mother Kelsey Berreth.
Authorities are currently looking for possible relics on the Midway landfill near the town of Wigwam, a month after she accused her fiancée Patrick Frazee of her murder.
"The Colorado Bureau of Investigation has contacted Waste Management of Colorado about a possible search at Midway Landfill and we are fully cooperating," said a spokesperson for Waste Management when asked for comments.
ABC News was the first to report this new development.

A friend of Frazee, whose granddaughter was a frequent playmate of the accused murderer's daughter Kaylee, told CNN that Frazee and Berreth had retired on New Year's Day in 2018, just three months after the couple had welcomed her daughter Kaylee.
This contradicts the remarks of Berreth's aunt who suggested that her niece had broken with Frazee on 22 November, the day she was last seen in public.
The authorities have since accused Frazee of first-line murder despite the fact that Berreth's body and remains have yet to be found.
The defendant and his legal team were only able to see the arrest document late in the month, a full ten days after Frazee was taken into custody.
At the same time, a woman from Idaho has reportedly become a person of interest in the research.
Two people who worked with that Idaho woman, Krystal Lee, say she and Frazee had been in a romantic relationship for months.
The 32-year-old nurse is supposed to have thrown Berreth's phone in Idaho in the days after she was last seen alive.
DailyMail.com spoke to two people who know Lee professionally, and they both said that they had been told that Frazee had an affair with the woman.
Lee was separated from her husband a few years ago, they explained and had met Frazee at a rodeo.
It is almost a month since the police Patrick Frazee imposed the murder of Berreth, despite the lack of evidence of a body or its remains
Neither person knew exactly when the relationship started, but they believed it could have been in 2016 – prior to the birth of Frazee's daughter with Berreth.
One of the people with whom DailyMail.com spoke also said that Lee was around Thanksgiving in Colorado.
That would explain how Frazee could get the cell phone to Idaho without ever leaving the state.
Last month it was reported that the police in Idaho had found information regarding the mobile phone of the missing mother.
The Twin Falls police station revealed that officials of the armed forces played a role in the investigation by obtaining search warrants and investigating evidence in the case.
Berreth & # 39; s cell phone panned a tower in Gooding, Idaho, on November 25, three days after she was missing, and around the same time her employer received a text stating that she did not want to go into service that week. The location where he piste is about 800 miles from where Berreth was last seen.
The affair revelation comes three days after Patrick Frazee was formally charged with assassinations in the case, though no extra arrests have been made in the month since he was taken into custody.
The complaint filed in the case, however, stated that Frazee had plotted Berreth's murder with at least one other individual in the three months before she was missing.
And while the authorities still need to discover a body or one of Berreth's remains at this moment, prosecutors said that the investigation provided enough evidence to indicate the two ways in which the 29-year-old mother was murdered by her fiancé.

The custody of the 15-month-old baby was granted to Berreth's parents after officials had announced that they believed the missing mother, 29, was dead.
That same day, her fiancée, Frazee, was accused of her murder.
The custody decision was, however, only a temporary decision, after Sheila Frazee had submitted a motion in which she stated that she wished to have the rights of the parents.
On the 27th of December, the Temporary County Department of Human Services issued a temporary emergency forgery warrant that placed Kaylee in temporary physical custody with her maternal grandparents, while TCDHS was legally guarded.
A follow-up hearing earlier this month continued until February and the Berreths will retain the custody of Kaylee until that time, although the girl's legal guardian remains the state.
Sheila has remained a staunch defender of her son, despite not having spoken publicly once.
The mother-of-three is at all hearings of her son, has submitted the guardianship movement and has lived alone with Frazee on her 35-acre farm for the past 20 years.
She was also detained when her son was arrested but never accused or accused of having been involved in the death of Berreth.
Frazee had provoked the murder for almost three months, according to court documents.
The three counts of Solicitation to Commit Murder in the First Degree all state that & # 39; between and including September 1, 2018 and November 1, 1818, Patrick Frazee unlawfully and criminally persuaded another person, prompted, begged or in another way has tried the crime of murder in the first degree. & # 39;
That would have been only a few months after Berreth had bought a house in Woodland Park for her and her daughter Kaylee.
She spent $ 184,900 on a two-bedroom house about 25 km from the ranch where Frazee lived with his mother, despite the fact that the two were engaged.
In that house, authorities believe that Berreth was murdered on or around November 22nd.
Berreth was last seen in a Safeway store in Woodland Park on Thanksgiving.
