reports The Sun. May, 67, — the mother of Driver’s wife, Joanne Tucker — allegedly taught classes for the Odyssey Study Group (OSG) which was allegedly founded by “Slaughterhouse Five” star Sharon Gans and her playwright husband Alex Horn and has a history of mental abuse, physical abuse, homophobia, racism and child abuse.According to several former members of the cult, members of the group were asked to fork over $400 per month to attend “lectures” hosted by Gans as well as classes based on the work of two Russian philosophers who believed hard labor and suffering was the way to self-improvement.“We would pretty much work around the clock the whole weekend for 48 hours and I was probably working 100 hours a week,” said survivor Don Raskopf. “After about six months of that, I learned I had a psychotic break just from the stress.”Spencer Schneider — who married May under the instruction of Gans until 2009 — claimed the leader would force people to reveal their greatest insecurity or fear so others could verbally assault and berated them.
