A Sanostee man has pleaded guilty to voluntary manslaughter and assault charges and could be facing a 15-year sentence in a New Mexico federal prison.
Prosecutors say 43-year-old Roderick Talk entered into a plea agreement Tuesday in Albuquerque.
Talk was arrested in June and charged in a criminal complaint with killing a man in New Mexico's San Juan County on May 30.
Prosecutors say Talk and the victim argued while drinking and that led to a fatal assault.
Talk also was accused of trying to injure the victim's nephew with a pickup truck on the Navajo Nation.
