A Minnesota man who threw his ailing wife a drug-fueled “death party” has been sentenced to three years behind bars after copping to a plea deal, according to a report.

Duane Arden Johnson, 59, who pleaded guilty to criminal neglect in June, was sentenced Monday in a plea deal approved by Judge Robert Docherty, according to the Mankato Free Press.

He was given credit for 201 days already served in the slammer. A charge of third-degree murder was dismissed in the plea deal.

Johnson told investigators that his wife, Debra Lynn Johnson, 69, begged him to take her home to die in January — and they held a “death party” that included taking methamphetamine.

A naked Johnson ran outside, yelled that his wife was dead — and then hurried back into the home, according to the police report.

Police found him in a bathtub, where he said he was trying to cleanse little white and black “things” from his skin. They also found 47 guns and hundreds of rounds of ammunition.

During the days-long death party, the couple rocked out to their favorite song, Quiet Riot’s “Metal Health” — and abused meth.
