More than a year ago, a plane carrying Poland’s president and many Polish dignitaries crashed in Smolensk, Russia, killing everyone on board. The airplane was heading to the Katyn Forest to recognize the 70th anniversary of the Russian massacre of 22,000 Poles during World War II. Among the dead was Chicago sculptor Wojciech Seweryn. He’s known locally for his sculpture in a Niles cemetery that honors the Katyn Massacre.

Wojciech’s daughter, Anna Wojtowicz, also lives in the Chicago area. She says the investigation of the Smolensk plane crash left a lot of unanswered questions. In a recent conversation, Wojtowicz explains her thwarted efforts to find out what happened to her father.
