Bartiomiej R. Barczyk, known as Bart, was 41 when he was fatally stabbed on December 4, 2016, in the Jefferson Park neighborhood of Chicago. The attack took place in a residential area; what led to the stabbing and the circumstances around it remain unclear.

Those who knew Bart remembered him fondly, and his death prompted vigils and memorial services attended by friends and family. The killing was one of many that pushed Chicago’s homicide total above 750 that year, a spike linked in public discussion to increased gang activity, economic instability, and limited resources for crime prevention in some neighborhoods. No suspects have been publicly identified or apprehended and the case remains under investigation.

If anyone knew Bart, witnessed the incident, or has information that could help investigators, please come forward to assist his family and the ongoing investigation.
