CROWN POINT, Ind. (AP) — A woman convicted in the killing and dismemberment of a man in Michigan's Upper Peninsula has pleaded not guilty to charges she later gave her husband a fatal heroin overdose in northwestern Indiana.

A Lake County judge on Wednesday scheduled a July trial for 35-year-old Kelly Cochran on murder charges for Jason Cochran's 2016 death in Hobart. The Post-Tribune reports court documents say Kelly Cochran told investigators she killed her husband because he took "the only good thing" in her life with the 2014 attack on her boyfriend Christopher Regan in Iron County, Michigan.

Cochran was sentenced last year to life in prison for Regan's death. Prosecutors maintained she lured Regan to her home where Jason Cochran shot Regan and then helped dismember and hide his remains in the woods.
