Patrick Frazee allegedly threatened his mistress over murder plot

An Idaho couple who called the FBI with information regarding the disappearance of Kelsey Berreth have newly claimed her ‘killer’ fiancé threatened his mistress over a possible murder plot.

Joe and Patty Rockstahl, owners of Rockstahl Law Offices, said one of their employees, who is a close friend to mother-of-two Krystal Lee, informed them about Patrick Frazee’s alleged threats.

When asked by CBS News correspondent Nikki Battiste about nature of the threats, Patty said: ‘Patrick told Krystal that little girls go missing off the playground all the time.’

Frazee has been charged in the murder of Berreth, who was last seen on Thanksgiving Day. Berreth’s body, however, has not yet been found.

Joe said: ‘Krystal was so scared… he was so angry that he said things that made Krystal think he had killed before. So of course, she’s going to be terrified.’ 

Patty told CBS that Lee and Frazee became romantically involved just after high school and that Lee was ‘in love with him’ for years. 

‘She was very vulnerable and I think she cared for him, and he took advantage of that… he was her first love, I understand, and… he had a hold on her.’

Federal officials are currently investigating whether Lee played a role in the disappearance of Berreth. 

The couple told KMVT that last October, that the employee came to them visibly upset and explained their her best friend told her that ‘a man had asked her to kill the mother of his child.’

The friend of the employee is now known to be Lee, the divorced mother-of-two who was having an affair with Berreth’s fiance Frazee. 

The Rockstahls said they told their employee to have Krystal come speak to them, but she never did.

They said at one point, Krystal told her best friend ‘to forget the whole thing’. 

The couple said they felt they didn’t have enough information at the time to report anything to the police.

It wasn’t until Patty saw Kelsey’s mother’s plea to find her daughter on national television that she began to connect the dots with the information she had learned. 

‘I think [it was] the mother that had the courage and go on TV when her daughter was missing, saying that someone knew where she was at,’ Patty told KMVT.

‘At that point in my mind I thought that Patrick, and that was the only name I had heard him called, I didn’t know his last name, had done something to her daughter and he knew where she was at,’ she added.

Within four days of making the call to the FBI, Patrick Frazee was arrested. 

The Rockstahls said they are telling their story now after their employee faced harassment on social media due to misinformation circling around. 

They now hope that anyone else with more information on Berreth will come forward.      

The Colorado Bureau of Investigation Department of Public Safety was investigating remains discovered near the town of Aguilar on Sunday, but have confirmed they are not those of Berreth. 

Frazee was served notice on Monday that a complaint had been filed by Cheryl and Darrell Berreth claiming he ‘enacted physical, mental, and emotional acts of violence upon Kelsey Berreth prior to her death.’

The complaint goes on to state that ‘when Frazee acted as either the perpetrator or accessory to the murder of Kelsey Berreth, Frazee breached the duty of care with which a reasonable person should conduct himself toward another human being.’

The Berreths, who currently have temporary custody of their daughter’s 15-month-old child with Frazee, are demanding a jury trial to determine and ‘compensatory and general damages, interest from the date of Kelsey Berreth’s death as provide.’, as provided by law.’ 

They have retained Perry Sanders to represent them in the case, the same man who represented Katherine Jackson after the death of her son Michael.

Cheryl and Darrell Berreth are suing Patrick Frazee for the death of their daughter Kelsey, who was last seen on November 22 (the Berreths above in 2014)
