Ismael Santana was a 70-year-old man killed in Chicago on December 10, 2007. His death occurred during a year marked by multiple incidents of street violence in the city that sometimes targeted elderly victims.

Initial police suspicion fell on Yesenia Santiago, but those accusations were later shown to be wrong when records established Santiago had been incarcerated at the time of Santana’s death. That error and the subsequent nearly two-year wrongful imprisonment of an innocent person became a focal point for criticism of investigative practices and use of incomplete information.

The precise circumstances of Santana’s killing remain unresolved, and his death is among several cold cases from that period in Chicago’s late-2000s homicide record.

Did anyone in Chicago at the time have information about Santana’s movements or potential witnesses from December 2007?
