Federal and tribal charges have been filed in connection with the fatal shooting of a Navajo Nation police officer.

Johnson Bigman, 25, and Tyson Bigman, 21, are brothers. They pleaded not guilty in tribal court to charges of disorderly conduct, homicide, accomplice to aggravated assault and criminal nuisance for the death of Sergeant Darrell Curley.

Separately, their father, Victor Bigman, 48, has been charged in federal court with first-degree murder. He is alleged to have shot and killed Curley.

The incident began when the brothers were intoxicated and fighting, according to the tribe. Their mother called the police and Curley responded, along with another officer.

The brothers resisted arrest, according to the tribe. That's when their father allegedly got involved in the altercation and when Curley was shot.

The incident took place late Saturday night in Kaibeto, Arizona.
