EAGLE — Eagle County prosecutors say they haven't decided whether to charge a 13-year-old boy accused of killing his father and concealing the body for nearly a week as a juvenile or as an adult.

The Vail Daily reports (http://bit.ly/1pNvEwb ) that the 13-year-old boy is accused of shooting and killing 50-year-old Joseph Kelly, Jr. Police say the boy called in sick for his father several days in a row, and that the death wasn't discovered for six days.

The boy is being held in a Jefferson County juvenile facility and made a third court appearance Monday. He was unshackled, with his mother and fellow classmates in attendance.

District Attorney Bruce Brown says prosecutors are still trying to determine whether he will be tried as a juvenile on first-degree murder charges.
