New details are still emerging in the case of 29-year-old Kelsey Berreth, the Colorado mother who was last seen on Thanksgiving Day this past November. Developments over the past few weeks have seen her fiancé, Patrick Frazee, arrested and charged in her murder even though officials are yet to find a body, and recently revealed court documents state he had been planning her death for at least three months.

Frazee was charged with two counts of first-degree murder and three counts of solicitation to commit murder in the first degree. According to the Daily Mail, the three latter charges state that "between and including September l, 2018 and November 1, 2018, Patrick Frazee unlawfully and feloniously commanded, induced, entreated, or otherwise attempted to persuade another person to commit the felony of murder in the first degree."

The dates coincidentally happen to fall a few months after Berreth purchased a $184,900 two-bedroom property about 15 miles away from where Frazee lived with his mother. The move was perceived to be odd as Berreth had moved to the state from Washington to be with Frazee but seemingly refused to live with him despite being engaged to be married and sharing a daughter with him.

There were seemingly tensions in their relationship, with a family member of Berreth claiming soon after the 29-year-old went missing that she had split with Frazee the day she was last seen. This, however, was never confirmed by investigators.

There were a series of other clues that seemed to point towards Frazee being the culprit as well. For one, he never reported his fiancee missing even though he admitted to detectives he saw her on the day she went missing to take their daughter from her. He was also later spotted acting suspicious and dumping trash from a trailer that was attached to the pickup he had driven to a nearby waste management facility.

Frazee was eventually arrested on December 21 and charged, with prosecutors revealing on New Year's Eve that they had two theories regarding how the mother was murdered, including one that suggested she may have been killed as a result of a robbery.

But other details have been kept under wraps and the arrest warrant has remained sealed because they fear publication of the details could "seriously jeopardize the physical safety of potential witnesses in the investigation". However, Frazee and his lawyers will be allowed to see the warrant and will likely take a decision on whether to enter a plea or not in the case depending on its contents.

What is already known is that Frazee will be fighting the first-degree murder charges and has asked that all evidence in the case be turned over to his legal team. He has also filed a motion asking to limit pretrial publicity.
