This episode is rated a 4 (on my Serious Crime Scale). It’s the story of Cindy Song, a 21-year-old senior at Pennsylvania State University, more commonly known as simply Penn State. On Oct. 31, 2001, Cindy went out with a couple of girlfriends, dressed in a bunny costume for Halloween. But when her friends dropped her off at her apartment in the early morning hours of Nov. 1, 2001, it would be the last time anybody saw Cindy… ever. To this day, there is still no trace of Cindy, and her case remains open and active, but still cold nonetheless.
