SIOUX FALLS, S.D. (AP) - A 30-year-old Sioux Falls man has pleaded guilty to manslaughter in the 2011 shooting death of his next-door neighbor.

KELO television reports that Peter Mayen could face up to life in prison for gunning down 51-year-old Bruce Walters, who died on his porch last October.

Prosecutors are dropping a charge of first-degree murder in exchange for Mayen's guilty plea to first-degree manslaughter. Mayen during a court hearing Friday admitted firing five rounds at Walters.

Police say there had been bad blood between the two men for months.

Sentencing is scheduled for November.
