I was a friend and colleague of Gerry through the addictions faculty INCASE which he was President of in the mid 1990s. He did a marvelous job. I also was a coauthor of a book that we had a hard time getting published. He visited me in Brooklyn shortly before he vanished. I and his friends could not figure out what happened to him. A year later he had an accident not far from here and passed away, which I saw in the local papers. We never fathomed why he disappeared during that year. We wished he had remained with that book. More so, we missed his presence and friendship and energy. A terrible mystery.
