Jimmy Brink did not decide on his own to sellout to Cleveland. It was after a 2nd attempt on his life. He decided it was not a deal that could be refused.

"The Cleveland Syndicate made a deal with the Kefauver Commission in 1952.
They would close the Lookout House if the Kefauver Commission would leave Beverly Hills and their other joints untouched. The Kefauver Commission took the deal. Beverly ran until 1961 and the April Flowers scandal finally put an end to Clevelands control over N KY gambling."

The man that engineered the deal with The Kefauver Commission was Moe Dalitz. He was the man in Cleveland, By the time the deal was made he had moved on to LV and was to become known as "The Father Of LV." He built hospitals, country clubs, The DI, Stardust, Sundance, to name a few.

One more tidbit:
The April Flowers scandal that closed KY illegals after 30 years involved a former Quaterback for the Cleveland Browns, George Ratterman. He was running for Sheriff of Campbell County. He would not be bought and is a story in itself.

The history of the KY illegals is very much entwined with the history of LV.
Many other people that started in the KY illegals in the 1930's went on to be part of the the ownership and building of The Sands, the Dunes, The Pioneer, The Four Queens and so on and so on.
KY and LV joints were very much entwined.
