A domestic dispute in Overgaard, Arizona, on July 1, 2019, ended with James Mellen Jr., 58, found dead in his bed from a gunshot wound. Deputies from the Navajo County Sheriff’s Office located him at about 10:00 PM after what is described as a daylong verbal and physical altercation between Mellen Jr. and his father.

Authorities reported that the 84-year-old father, James Mellen Sr., shot his son with a pistol after the younger Mellen had gone to bed. Mellen Sr. was arrested and booked at the Navajo County jail on suspicion of first-degree murder; the case was referred to the Navajo County Attorney’s Office for review.

Are there any witnesses or neighbors who heard or saw signs of the argument that day and haven’t yet spoken to investigators?
