William Zientek, an ex-partner of Dr. Olga Duchon, a Lake County endocrinologist, is accused of killing her in Barrington. Zientek claims self-defense, arguing Duchon threatened him with a gun, but her family disputes this, saying she didn't own guns and that he hit her with a baseball bat first. Zientek, who had a protection order against him, is charged with first-degree murder, using a stolen gun. He remains in custody, with an arraignment scheduled for January 9th.
