The lawyers for Patrick Frazee, the Colorado man accused of murdering Kelsey Berreth, may be looking to pin the crime on someone else.

The Denver Post obtained court documents showing that prosecutors filed a motion to “require the defendant to endorse alternate-suspect defense if he intends to present such evidence at trial.”

The documents do not identify an alternate suspect by name. But Frazee’s onetime girlfriend, Krystal Kenney, is a key witness in the murder case, and took a plea agreement admitting to one count of tampering with physical evidence in exchange for testimony against the suspect, who is the father of Berreth’s toddler daughter.

Kenney, a nurse who lived in Idaho at the time that Berreth went missing, reportedly told investigators that Frazee murdered Berreth in her Woodland Park home on Thanksgiving Day, the last day she was seen alive. According to her account, Frazee demanded that Kenney drive from Idaho to Colorado in order to clean up the bloody crime scene, which she said she did on the Saturday after Berreth’s murder.

Berreth’s body has not been found, despite an extensive search of a landfill that appears to have been prompted by Kenney’s testimony that Frazee burned the victim’s remains on his property.

Kenney also claimed that Frazee had asked her to kill Berreth on three occasions prior to her presumed death, and admitted that she considered it before changing her mind. 

Frazee’s murder trial is set to begin on October 28.
