GILLETTE (WNE) –- A Gillette man pleaded no contest to one count of manslaughter Wednesday.

Joshua Lewis Campbell, 22, was charged in the June 2, 2020 death of 21-year-old Tanner Miller.

District Judge Thomas W. Rumpke called the incident  “incredibly stupid gunplay by young men who did not realize their own mortality.”

An affidavit in the case said Miller, Campbell and another friend had gone to the apartment after having dinner with another friend. At about 9 p.m., they left to buy more alcohol and then went back to the apartment. Before Miller parked the vehicle, he let Campbell and the other man out so they could get into the apartment.

The two “as a prank, locked the apartment door and shut the lights off,” according to the affidavit. “They were going to use rifles to scare Miller when he came in.”

The other man checked the 30-30 rifle he had to make sure it wasn’t loaded but didn’t know if Campbell checked the AR-15 he had, it said.

“Campbell then unlocked the door and Tanner walked into the apartment and turned on the lights,” according to the affidavit.

Campbell then reportedly fired a shot at Miller, according to the affidavit. A forensic pathologist estimated the rifle was fired no farther than 3 inches from the left side of his head.

Campbell, who had a blood alcohol content of 0.103%, told police that he thought it was an intruder.

In October, Campbell pleaded not guilty. On Wednesday, he pleaded no contest in a change of plea hearing.  He will remain out on bond until he’s sentenced.

Sentencing is scheduled for Oct. 14. Manslaughter carries a maximum penalty of 20 years in prison and a $10,000 fine.
