Box Elder Man Pleads Not Guilty to Second Degree Murder

BILLINGS, Mont. (NMB) – A Box Elder man was arraigned in U.S. District Court last Thursday on the felony charges of second-degree murder and assault resulting in serious bodily injury.

A jury trial has been tentatively set to begin on January 11th, 2021.

If convicted of the most serious crime, Blackwolf faces a maximum life in prison, a $250,000 fine and five years of supervised release.

Blackwolf was detained pending further proceedings.

The FBI and Bureau of Indian Affairs investigated the case.
