Did Earl Ruby change the name of his business from Cobo Cleaners to Ruby Cleaners about the time of the 1991 release of the movie "JFK"? Is the cleaners on Livernois near U. of Detroit campus still in business and, if so, is it still called Ruby Cleaners?

Is Earl Ruby still alive? The last I read about him he was living in Delray Beach, FL in the '90s. That is where is said to have fired a number of rounds from Jack's infamous pistol into a drum of water. Earl then offered the bullets up for sale as historic souvenirs.

Anyone know Earl Ruby personally?
