SIOUX CITY, Iowa (AP) — A woman sentenced to life in prison for killing her neighbor as part of a plot to frame her ex-husband is appealing her conviction. Lawyers for 45-year-old Tracy Richter filed notice of an appeal on Thursday. Richter was sentenced in December for fatally shooting 20-year-old Dustin Wehde in her Early, Iowa, home in 2001. In national television interviews after the killing, Richter claimed that Wehde and another man had broken into her home.

But jurors sided with prosecutors who believe Richter made up the attack. Prosecutors say Richter killed Wehde to keep him quiet about his role in a plot to frame her ex-husband. Richter, who lived in Omaha, Neb., before her trial maintains her innocence.
