Gregory Shanks, 47, was fatally stabbed on March 19, 2014, inside an apartment building in Chicago’s Humboldt Park neighborhood on the 700 block of North Trumbull Avenue. The attack followed an argument with another individual and Shanks was stabbed in the chest just before 3 p.m. He was taken to a nearby hospital but died shortly thereafter.

The killing was one of several violent incidents reported in the area between March 13 and March 20, 2014, a period that underscored the city’s high homicide rate and concerns about neighborhood safety. Beyond the basic facts of time, place, and cause of death, little else is provided about the person who attacked him or about any subsequent investigation.

Did anyone in Humboldt Park in March 2014 see or hear anything that could help explain what happened to Gregory Shanks?
