So-called “Doomsday Mom” Lori Vallow Daybell,

At the time of Charles Vallow’s murder, his daughter, Tylee, confronted him with a baseball bat after hearing screaming inside the house. Charles reportedly took the bat from Tylee, who told police she was trying to protect her mother, and allegedly tried to attack Cox. Cox told investigators he fired his gun in self-defense and was never charged in Charles’ death before he died of natural causes months later. 

Vallow Daybell could face another life sentence if convicted and is also facing another Arizona trial in May for an alleged plot to kill her niece’s ex-husband after a judge denied her motion to dismiss the case.
