Broderrick Ramon Coggeshell, 38, of Chinle, was sentenced on Monday by United States District Judge Michael T. Liburdi to nine years in prison, followed by three years of supervised release. Coggeshell pleaded guilty to Involuntary Manslaughter and Assault Resulting in Serious Bodily Injury on January 30, 2024.  

In December 2022, Coggeshell, while intoxicated, crossed the center line of traffic with his truck and collided with a vehicle occupied by three brothers, killing one and seriously injuring another. Coggeshell and the victims are all members of the Navajo Nation.

The Navajo Nation Criminal Investigations Division conducted the investigation in this case. Assistant U.S. Attorney Kiyoko Patterson, District of Arizona, Phoenix, handled the prosecution.
