The state never dumped anyone over the side of a boat in the East River.

 Norristown, PA? 

Someone went to a lot of trouble to explain the situation in Norristown. For years I've seen "Numbers" games mentioned in mob movies but never understood. This explains it well. (Thx) It seems like this person had first-hand experience with the people in this racket. Has anyone written a newspaper article or book that could be used as a more traditional source?
