Scott Butvilas, 40, was found severely beaten in the 3400 block of West Chicago Avenue in Chicago on July 5, 2011. He died of those injuries on July 12, 2011; the Cook County Medical Examiner ruled his death a homicide caused by multiple injuries sustained in the assault.

The case occurred during a year of high levels of violence in Chicago, when the city recorded over 433 murders. Investigators faced the same difficulties noted in many 2011 cases, including limited witness cooperation and few clear leads in some violent incidents.

Does anyone who lived or worked near West Chicago Avenue in July 2011 have information that could help explain what happened to Scott Butvilas?
