Do you have a source to link Edward O’Hare to Capone regarding anything other than the dogtrack(s)?

Also when it comes to Hot Springs, AR:
What source do you have linking him to ownership in the Belvedere Club or Oaklawn Park? There were atleast 6 more casinos, why no stake in them?

He had a room rented year round on the fourth floor (412 or 442) at the Arlington Hotel in Hot Springs.

Not saying I dont believe you I would just like to see the sources. Gambling in Hot Springs was only allowed because it was home grown, not brought in by out of town gangster elements.

The only famous gangster I've ever found to have interests in Hot Springs casinos is Owney Madden, who lived there for decades and is buried there. Over the years he had up to 25% interest in almost all of the casinos, at various times. He also fought for control of the wire service with the local politians.
