Prosecutors: Armed robbery plot by man, teen turned deadly in Minnesota home

Prosecutors say a robbery plot by a man and a teenager turned deadly in a northwestern Minnesota home over the weekend.

Arthur Deshun Campbell, 21, and Kayne Nobel Mackner, 16, were each charged on Dec. 22 in Becker County District Court with second-degree murder in connection with the shooting early Dec. 20 in Frazee that killed 19-year-old Bryson Andrew May.

Campbell, of Frazee, and Mackner, of Detroit Lakes, Minn., were both arrested on the day of the shooting. Campbell is due back in court on Feb. 9, while Mackner has a Jan. 6 court date scheduled. The Minnesota Star Tribune has reached out to attorneys for both defendants for responses to the allegations.

The County Attorney’s Office has notified the court of its intention to prosecute Mackner as an adult.

May was shot about 2:35 a.m. in a duplex in the 700 block of W. Ash Avenue, taken by emergency medical responders to a nearby hospital and pronounced dead there, the Sheriff’s Office said.

According to the charges and the Sheriff’s Office:

Deputies found out that four people left the duplex in a black SUV. A sheriff’s deputy in neighboring Otter Tail County spotted the SUV about 9 miles to the southeast of Frazee near Perham shortly afterward.

The driver of the SUV, a teenage boy, told law enforcement that Campbell and Mackner went to the duplex to confront someone who lived there and owed them money.

The teen said he stayed in the vehicle while Campbell and Mackner went in the home, and shots were soon fired. He said he drove off once Campbell and Mackner got back in the SUV.

On the afternoon of his arrest, Campbell told investigators that he has “flashes” of what occurred in the home, the charges read. He said recalled firing one shot and that he was aiming at May’s leg because he didn’t want his victim to chase after him.
