According to Radar Online, Colorado's mother, Kelsey Berreth, was killed by her ex during a battle for the custody of a child, according to her parents. Berreth's parents claim in an amended lawsuit that their former fiance Patrick Frazee may have killed her to get sole custody of their one-year-old daughter, Kaylee. Frazee faces a charge of first degree murder although Berreth's body was not found. Berreth, 29, was last seen on Thanksgiving Day. Krystal Lee Kenney, who had a relationship with Frazee, recently declared in court that she had destroyed Berreth's mobile phone after her alleged involvement in her death, according to Radar Online. Frazee reportedly asked for help to kill Berreth.
