GYPSUM, Colo. - Investigators say a 13-year-old boy fatally shot his father and tried to conceal the slaying from authorities, living alone in the family's Colorado home with the body for nearly a week, reports CBS Denver.
The boy is charged with first-degree murder but he is being held in the juvenile facility in Jefferson County.
CBS Denver reports the teen is alleged to have used a rifle to kill his father sometime around April 29 or 30 in the home they shared in Gypsum, a small town in western Eagle County.
The teen allegedly fired at least two shots, reports the station.
"There was one to the back of the head and one to the temple," Eagle County coroner Kara Bettis said, according to the station. "The one to the temple was contact and the one in the back of his head was from farther away."
The station reports the teen allegedly called into his father's work every day after his death, reporting him sick. After a few days, his father's supervisor at the county-run transit department where he worked became suspicious and called police.
"He had been dead for around six days," Bettis reportedly said.
It wasn't until a deputy showed up at the house that the boy admitted his father was dead inside.
"The juvenile answered the door and told deputies that his 50-year-old father was deceased in the residence," Eagle County Sheriff Joseph Hoy said, according to CBS Denver.
Police say the motive remains unknown.
Hoy said authorities have only been called to the family's house once before - a year ago - for a domestic dispute between the parents.
The sheriff's office told CBS Denver the teen's mother was not living in the home with her son and ex-husband at the time of the crime.
