Albert Hsu, 43, a wealthy, married dad of two and former Cub Scout leader, posted his fiendish ad on a hardcore, S&M Web site, Connecticut authorities said.
He allegedly included the woman's name, photo, address, license-plate number, train schedule to and from work and even the rail car she usually sits in.
"The defendant set the victim up to be abducted and raped by a complete stranger," prosecutor Ricki Goldstein said in Norwalk, Conn., Superior Court.
