Looking for Information on John David Norman's "Delta Project" and Illinois Connections

Hello everyone,

I'm an independent researcher currently looking into John David Norman, a convicted sex trafficker who operated multiple organizations and front groups during the 1960s and 1970s. One organization frequently mentioned in historical reports is the Delta Project, which was directly operated out of Chicago.

I'm attempting to locate:

• Information on where the organization operated in Chicago or elsewhere in the state
• Court records, police investigations, or public documents related to Norman and his associates
• Personal recollections from anyone familiar with the case or who remembers media coverage at the time
• Information about related organizations, including the Odyssey Foundation and other groups linked to Norman
• Former journalists who investigated Norman, the Delta Project, or related cases.
• Retired law enforcement officers, prosecutors, social workers, or court personnel who may have worked on investigations connected to Norman.
• Historians, researchers, or archivists familiar with Chicago vice investigations, child exploitation cases, or organized crime during the 1960s–1980s.
• University, nonprofit, or private archival collections that may contain correspondence, notes, clippings, photographs, or unpublished research.
• Individuals who remember the Delta Project's operations in Chicago or have family members who were involved in related investigations.
• Leads on local organizations, community groups, or advocacy organizations that may have documented the case at the time.

I've already reviewed a number of publicly available sources, but much of the information online is fragmented, contradictory, or difficult to verify. My goal is to separate documented facts from rumors and build a better understanding of the historical record.

If you know of archives, libraries, local historians, newspaper databases, or other resources that might help, I'd greatly appreciate any leads.

Thank you.
