Anyone who traveled regularly past the DeMaio home on Round Hill Road was bound to note its most prominent feature, the huge fountain in its front yard. Who puts fountains in the front yard of their New Jersey mansions? The Mafia and the Russian mob, that’s who, and while you can move a Jersey mansion to Greenwich – especially a pre-fab one, you can’t leave the mobster behind. Doubt this? Well here, just as a for instance, is the home where penny stock fraudsters Alan Chalem and Mayir Lehmann were killed by Russians in 1999 (I actually went after the victims once, but I used the NASDAQ arbitration process, not a 9mm).
