Kenney previously revealed she took several bloodstained items from Berreth’s home so that they could be burned. She claimed Frazee put his fiancée’s body in a dry water trough and lit it on fire. When the flames got too high, Kenney said he covered the container with metal roofing. Berreth’s remains have not been found.
During her sentencing hearing, Kenney expressed remorse, telling the courtroom, “The most important thing I have to say is how sorry I am… I am sorry Kaylee has lost her mother. I am sorry that I did not save Kelsey… My punishment comes every day.”
