The Man who Killed Halloween, and birthed an Urban Legend

On Halloween in 1974, a man named Ronald Clark O'Bryan would commit a horrific act that would have a continued impact over the next 5 decades and become the basis for the urban legend of strangers poisoning candy handed out to children on Halloween.  Now, while this urban legend has been mostly debunked, there are small bits of truth that help enforce the idea that people are using Halloween candy as a method to harm children.  We discuss these incidents over the years, as well as whether or not a myth can become reality over time.
