A former Idaho Death Row inmate who was exonerated of murder 17 years ago is headed back to prison.

Donald Manual Paradis, 69, served 20 years in prison for the 1980 murder of 19-year-old Kimberly Palmer.

Paradis was charged with aggravated assault for an incident involving a handgun in his Boise home in September 2017.

He was initially charged with four crimes but later pleaded guilty to the aggravated assault charge and a firearm enhancement.

Fourth District Court Judge Melissa Moody sentenced Paradis to serve at least three years of a 15-year sentence. She retained jurisdiction, meaning he could be released sooner depending on how things go in prison.
