A 22-year-old man is in the Umatilla County jail on murder charges after authorities found another man fatally shot on the Umatilla Indian Reservation Wednesday morning.

Joseph McIver is now facing murder charges for the 3:30am shooting  that occurred in the Meacham area along the Old Oregon Trail Highway.

Tribal Police, Oregon State Police and Umatilla County Deputies found 44-year-old Thadd Justin Nelson dead from a gunshot wound, and shortly thereafter arrested McIver.

The incident continues to be under investigation.
