The Cook County State's Attorney's Office announced an indictment Friday against a Barrington man accused of fatally shooting his estranged girlfriend last month.
William R. Zientek, 46, is charged with first-degree murder in connection with the Nov. 17 death of Vernon Hills endocrinologist Olga Duchon, the mother of her young child.
Zientek, who was taken to the Cook County Jail, will be arraigned Jan. 9 in Rolling Meadows.
After inviting Duchon to his home for an interview, prosecutors said Zientek hit her twice in the head with a baseball bat and shot her with a gun he had previously reported stolen. Zientek's lawyer Thomas Glasgow says his client acted in self-defense.
According to prosecutors, the couple was chatting in Zientek's living room when he beat and shot her. Officers responding to Zientek's 911 call found Duchon lying on her side with a child's blanket over her. They seized a 9mm pistol, spent cartridges and a baseball bat. In the attached garage, officers found a backpack containing 9mm bullets and an empty holster.
