The day Kelsey Berreth disappeared, her fiancé's mother wrote a chilling message on Facebook. Patrick Frazee, 32, was accused of beating Berreth to death with a baseball bat and then burning her remains on his ranch on Thanksgiving Day.

The search warrants from the case revealed a tip came in on Dec. 12 in regard to a post shared by Sheila Frazee, Daily Mail reported. The post, which was shared Nov. 22, featured a photo of the character "Glinda the Good Witch" from the "Wizard of Oz", and read: "YAY the witch is dead."

It is believed that the message was posted during the same time Frazee arrived home at his mother's house for Thanksgiving dinner after he allegedly murdered Berreth. The 29-year-old was last seen shopping on Thanksgiving Day and three days later, her cell phone pinged near Gooding, Idaho, just 40 miles from Twin Falls. While her body or remains were not found yet, police believe Berreth was murdered at her Woodland Park home. Frazee was the last person to see the flight instructor before she disappeared.

Frazee faces five counts of murder, including two counts of first-degree murder and three counts of solicitation to commit first-degree murder.

While gruesome details emerged in February as to how Frazee allegedly killed Berreth, her remains were yet to be found. Authorities are digging through a quarter-acre of the Midway Landfill in Fountain, Colorado, in hopes of finding the charred remains of Berreth’s body.

Investigators were led to the landfill by Idaho nurse, Krystal Lee Kenney, who was thought to be the alleged mistress of Berreth’s fiancé. Kenney was also accused of disposing of Berreth's cellphone. She was charged with one count of tampering with physical evidence.

As the search for Berreth's remains continue, Frazee filed a motion in court to dismiss Berreth's parents’ plea for custody of their daughter, Kaylee.

Berreth's family also filed a wrongful death lawsuit against Frazee. However, Frazee's legal team claimed that Colorado’s wrongful death statute clearly states that the Berreths have no standing to make a legal claim based on the alleged wrongful death of the mother-of-one.

“Only her living and surviving child, KF (Kaylee Frazee), has standing to bring a wrongful death claim,” a motion to dismiss the wrongful death lawsuit claimed. “In the original complaint, plaintiffs pled that the outrageous conduct of Mr. Frazee was the alleged killing and death of their daughter at his hands … But plaintiff’s attempt to save the claim fail and it must be dismissed.”

“Patrick Frazee is entitled to dismissal because Kelsey Berreth has a daughter, which, in fact, precludes Kelsey Berreth’s parents from bringing a wrongful death claim against him. And Colorado law does not permit more than one civil suit for the death of one person,” the motion said.
