Senter was a nobody, ya he got his button after switching over to the Lucchese from Gambino borgata but that was cuz casso needed more homicidal maniacs like himself. Senter as far as I know was a worker bee not a known earner but if told to kill would do so gladly.
you are right. Senter was involved in the stolen car ring,pornography,and drugs but Roy was basically the brains behind it all. Senter was a killer first and foremost
