Woman trying to gain custody of niece after Dr. Olga Duchon shot, killed in Barrington; girl's father William Zientek charged

ROLLING MEADOWS, Ill. (WLS) — A man accused of the murder of a doctor from the northern suburbs appeared in court on Friday. The family and friends of the victim were present to witness the proceedings in person.

And the victim’s sister is now trying to gain custody of the couple’s child.

Duchon’s family and friends vow to be at every hearing for the man accused of killing her.

“We’re committed to make sure this murderer in prison for the rest of his life,” sister Tatiana Maya said.

Zientek is charged with murder in the death of his former girlfriend and the mother of their 4-year-old daughter.

Prosecutors say Zientek hit Duchon twice with a baseball bat before shooting her.

Paul Wharton expressed, “Dr. Olga Duchon was an exceptional human being. She dedicated herself wholeheartedly to her patients and her family. That’s why we are all so heartbroken.”

Zientek’s attorney claims Duchon brought a gun to his Barrington townhouse, where they were to meet to discuss child custody.

And during a struggle over the gun, it discharged, killing her, the attorney said. It happened in the presence of their daughter.

Attorney Tom Glasgow remarked, “This is a heartbreaking situation as the mother of his child has passed away, something he neither anticipated nor desired as an outcome.”

Her family says Duchon hated guns, and filed an order of protection against Zientek in 2021, requiring him to surrender his firearms. Relatives now say they’re trying to protect her child.

“Her daughter was everything to her, her daughter and her work, everything,” Maya said.

The case is due back in court early next month.

Duchon’s sister said she plans to be in a different court later next month, asking for permanent custody of the couple’s child.
