Prosecutors have officially filed a murder charge against a Phoenix couple in the shooting death this week of their 9-year-old son.
Wendy and Kansas Lavarnia are each charged with first-degree murder, child abuse and hindering prosecution in the death of their son Landen.
Court records don't show that the parents have yet been assigned attorneys.
Police say Wendy Lavarnia told investigators that her 2-year-old son found a gun left on a bed and accidentally shot his brother.
Investigators became suspicious when they found inconsistencies in the mother's account and when the boy's father showed up at the home with a gunshot wound to his upper arm.
Authorities have declined to say who they believe is responsible for shooting the boy and his father.
