I just started reading this article and realized that I knew Denny back in the 90's. I was attending the Art Institute of Houston and one of my class mates dated Denny. They were actually in a serious relationship. After i left school and relocated to another state, I heard that my class mate Michael Holstein had disappeared and I am not sure if he was ever found. I always suspected Denny had something to do with it because he was very controlling of Michael. Denny also like the finer things in life. If I remember correctly he drove a vintage Mercedes convertible and acted as though he was a multimillionaire. Does anyone know about the Michael Holstein disappearance back in the 1990's and if he was ever found?
