Barrington man charged with murder after shooting of family member Dr. Olga Duchon: police

BARRINGTON, Ill. – A 46-year-old man has been charged with murder in the shooting deaths of a family member and a prominent doctor in what police described as a domestic incident in the northwest suburb of Barrington.

William Zientek, of Barrington, allegedly shot 42-year-old Olga Duchon, of Vernon Hills, in the chest at his home on November 17 around 5:40 p.m.

Duchon was taken to Advocate Good Shepherd Hospital, where she was pronounced dead. An autopsy conducted by the Lake County Coroner’s Office confirmed that Duchon died of a single gunshot wound to the chest.

Duchon, who practiced independently according to Advocate Health Care’s website, had given a presentation to the Ukrainian Medical Association of North America in Wheeling just hours before her death.

The association posted the following on Facebook:

“We are all shocked and saddened to hear of the tragic passing of our colleague Dr. Olga Duchon. Yesterday we had the pleasure of her company at our UMANA meeting. We extend our most sincere condolences to her family and friends.”

Barrington police said the shooting was a “domestic incident between family members” and there is no threat to the public.

Zientek is scheduled to appear in court on November 20 for a detention hearing.
