The Zodiac Killer terrorized the San Francisco Bay Area in the 60's and 70's and was never caught. Some 5 decades later, his identity may be coming to light:
"The identity of the Zodiac Killer is Jack Tarrance. He's my stepfather," says Dennis Kaufman. [...]
Jack Tarrance died in 2006. Dennis claims that while going through Tarrance's belongings, there were disturbing findings including a knife still covered with what could possibly be dried blood. "It could be a knife he barbecued with or a knife he murdered someone with," says Kaufman.
Jack also left behind rolls of undeveloped film. Dennis plans to hand over the film to the FBI. On one of the rolls Dennis did develop, there were numerous gruesome images. "Appeared to be people who were murdered," explains Dennis.

I always had fun scaring out of towners telling them the Zodiac was never caught and could still be wandering around. (though I always knew he was most likely dead)
