1. Secrets in a Small Town

By 1992, Ohio resident Bob Hand has been married four times. In 2002, fourth wife Jill, has been shot and killed, allegedly by Lonnie Welch, whom Bob then shoots during a break into their home. Strangely Bob Hand swears he doesn't know Lonnie Welch, yet later detectives discover Welch was Best Man at Hand's second wedding. Investigators, eager to find out more about Hand, seek out his ex-wives. To their surprise, two out of three have also been murdered, almost exactly the same way. The only surviving wife will not cooperate. Lonnie's family, however, will.
