Illinois couple killed, ex-son-in-law arrested after search March 17, 2021 FacebookTwitterEmail OTTAWA, Ill. (AP) — A man was arrested Wednesday for allegedly killing his ex-wife's parents and shooting out windows at his ex-wife's house, ending a search that had prompted authorities to urge residents of a small Illinois village not to go outside. At a press briefing, LaSalle County Sheriff Tom Templeton said that Donald Fredres, 37, of Sandwich, was spotted in a field not far from where the shootings occurred Tuesday night and was taken into custody shortly before 7 a.m. Wednesday. Templeton said detectives believe Fredres acted alone so that it was safe for residents in and around the village of Sheridan to return to normal activities.
