What's the Tucson Sound?

There was something called the Tucson sound, and we don't know what that means. The main documentary that we're going to be referencing in today's episode is a classic unsolved mysteries episode from January 1991. In that episode, they explain all of the reasons for this mob activity in Tucson at the time. Apparently, it was because of the warm climate. So either it's that or it's because of the actual growing drugs or it's just because mobsters like a temperate climate. I don't know.
