Journalist Gary Cartwright wrote about Jada in Texas Monthly (Dec 1990) text of article here
My friend Bud Shrake, who shared an apartment with me on Cole Avenue in 1963, recently refreshed my memory. Ruby and other characters from the Carousel Club, including an unforgettable stripper named Jada, hung around our apartment. After the assassination Jada told us Ruby once introduced her to Lee Oswald at the Carousel. While they were having drinks, Beverly Oliver, a singer from the Colony Club next door, stopped by and was also introduced. For some reason, I chose to forget Jada's story when I wrote about Ruby in 1975. Jada is dead now, but I phoned Beverly not long ago and asked if she remembered. "Sure do," she said. Ruby introduced him as 'my friend Lee from the CIA.'"
