Ok, fair enough. I am not certain, just curious.

According to newspaper reports and the Chicago Crime Coimmission, Aleman was a suspect in 13 murders.

I thought I read somewhere, that some of Aleman's murders were disclosed / confirmed by Nick Calabrese after he cooperated. Prosecutors decided not to take any to trial because Aleman was already locked up for life. It may have been a newspaper article that the FBI informed families of Aleman's murder victims based upon Nick Calabrese's disclosures.

Joe Ferriola was his uncle and with Aleman's murder count, I was under the impression he had his button.
