The state Supreme Court also rejected the appeal of the man who killed his girlfriend and two children.
Corey LaValley was convicted for three murders in March 2015. LaValley shot and killed 33-year-old Debra Sheppard, their ten year old son Corey Junior and Sheppard's 12-year-old daughter Emma McComber.
State investigators did not follow through with welfare checks of the two children, despite pleas from McComber's father.
He then returned to their home the next day to set it on fire.
LaValley was sentenced to 55 years in prison.
