(Monticello, IL) — It took a central Illinois jury less than three hours to decide a Piatt County man killed his wife back in 1990. Gregory Houser is now facing life in prison for the murder of his wife, Sheryl. Prosecutors say Houser killed her because they were divorcing and she was starting a new life. Houser’s lawyers pointed the finger of blame at a number of other people. Houser will be sentenced in September.
