Jay R. Polhill, a 20-year-old Columbia College student, was last seen at his residence hall in Chicago’s South Loop on February 28, 2010 and was reported missing for several days. His body was recovered from the Calumet River on March 2, 2010.

The death was initially listed as inconclusive, but subsequent investigation attributed it to drowning and multiple injuries sustained in an assault. Those findings made the case a suspected homicide and prompted questions about what happened during the days between his disappearance and the discovery of his body.

Few public details are available about Polhill’s activities or contacts in the hours before he was last seen. Does anyone have information about Jay’s time in the South Loop or what he was doing in late February 2010?
