Yes, I did read that the contractor who built Accardo's house was murdered, and the FBI did get the blueprints. Also, one of his neighbor's business's was torched after the neighbor allowed either the police or newspaper to photograph a party at Accardo's house. I believe it was like an annual July 4th party; could have been a Labor Day party, I'm not sure.

Don't get me wrong, all these guys should have been in jail. They were extortionists, thieves and killers. Giancana and Accardo were two of the worst. These guys were old-school, hardened gangsters and were fearless when it came to doing Outfit business.

Your opinion is as good as anybody's relative to Accardo, but I haven't come across any information that would indicate he was an informer. If I do I will certainly pass it on.
