Over the years, there have been several sets of cards with a "True Crime" them, featuring serial killers, murderers, etc.

If that's your thing, you might want to pick up this recently-discovered Menendez Brothers card.

Interesting find after all these years. I remember buying packs of those every day from the ice cream man in 1990 until I'd bought all of his packs. I definitely have a few sets of those cards, but they are from a wildly overproduced sets, so even with any new morbid interest in this dubious double (murderer) Rookie Card, it's hard to imagine there'll be any spike in the value of it from the 5 cent card it was before.
