Michael Marino was 14 when he disappeared from Chicago on October 25, 1976 and was long listed among the 33 victims of John Wayne Gacy. His mother, Sherry Marino, disputed that identification from the start, citing mismatches between what the autopsy reported and what she knew about her son — including clothing that did not match what he was wearing and a healed collarbone injury Michael never had.

In 2011 Sherry obtained a court order to exhume the grave. DNA testing on those remains showed they were not Michael Marino. The Cook County Sheriff’s Office challenged that result, saying additional testing by its laboratory was needed. With the body at the graveyard excluded, Michael’s actual fate remains unknown and questions have been raised about whether other identifications in Gacy’s case might be wrong.

What information, photos, or memories of Michael could help clarify where he was and what happened to him?
