Eric B Herner, a 41-year-old White man who ran a janitorial and home-cleaning business called The Man With The Mop, was killed on May 20, 2010, inside his apartment in Chicago’s Rogers Park neighborhood. Neighbors and family knew him from his Evanston roots and attendance at Evanston Bible Fellowship Church. He was born in Chicago on October 25, 1968.

Herner was found by his girlfriend that Thursday afternoon, lying in a pool of blood after having been brutally beaten and stabbed with tools. An autopsy determined the death was a homicide.

Police investigated but no contemporaneous public report named a suspect, and subsequent publicly reported accounts do not document an arrest, charge, indictment, trial, plea, or conviction in connection with the killing. Who attacked Herner and why remains unanswered. If anyone knew Eric, who was with him on May 20, 2010, or has information about this case, please share what is known.
