A federal jury convicted the last of four defendants in a murder on the Southern Ute Reservation in Colorado.

Isaac Headman, 27, was found guilty of first-degree murder, felony murder and kidnapping. He took part in the brutal killing of Clifton Joseph Greany, 31, in August 2007.

Headman, Greany and three women were drinking together when an argument over Indian heritage erupted. Greany, who was Cheyenne from Oklahoma, clashed with another member of the group, who was also from Oklahoma but from another tribe.

The three women pleaded guilty and agreed to testify against Headman. It was not reported whether Headman is a member of a tribe.

Headman faces a mandatory life sentence.
