FERGUS FALLS (AP) -- A former Fergus Falls man accused of killing his nephew over a drug debt has decided to enter a guilty plea, bring his trial to an abrupt halt.

Michael Alan Burris pleaded guilty Thursday to second-degree unintentional murder.

The 66-year-old Burris testified he and his nephew, Scott Burris, had an argument the day he was killed in May of 2012.

Burris says that Scott picked up his uncle's gun and pointed it at him.

Burris says when Scott put the gun down, he picked it up and fatally shot his nephew.

Burris' trial was scheduled to begin a third day Thursday before he agreed to a plea deal.

Reports say prosecutors have agreed to recommend 12 1/2 years in prison.

Sentencing is scheduled for December 19th.

Burris' son, Michael Kyle Burris, earlier pleaded guilty to helping dispose of the victim's body.
