Duchon, who practiced independently according to Advocate Health Care’s website, had given a presentation for 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. Just 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-related incident between family members" and that there is no threat to the public.

Zientek will appear in court on Nov. 20 for a detention hearing.
