The Irish Mob of the Quad Cities.

John Patrick Looney ran day to day operations based out of Rock Island, IL
In the 1920's. Anyone here have any info on this gentleman?

I live literally within walking distance of the Looney mansion. There's a book called "Citadel of Sin" by Richard Hamer that has all the information possible on the subject of Looney and his operation.The move "Road to Perdition" was a big deal around here, the house in the movie is a bit more massive and impressive than the actual Looney mansion that is in a bit of disrepair, but still an impressive place. 2 story library in the place with stained glass windows you can see from the street. His "lieutenants' house is on the property as well, but I think that has been owned for the same family for quite a while and is in good shape. When I was younger I worked at the hotel where Conner Looney was gunned down in front of. Both John and Conner Looney are buried in unmarked graves here in Chippiannock Cemetery.

I think Road to Perdition kind of made him out to be something more than he was. I don't believe he had a real working relationship with Capone and the Outfit. It seemed to me his main thing was extorting local businessmen and politicians by staging compromising photos (like having a prostitute sit on their lap in a bar) and threatening to run the photos in the local paper he was owner and publisher of. And he was more a political fixer type guy, than "gangster" in the sense of organized crime.
