Sadly, both clever and clumsy killers have always lived among us: could it be a neighbor? A family member? A co-worker? Are they capable of committing such a chilling crime? What drives deranged people to do away with someone, and then do it over and over again? We are going to find out what goes on in the mad mind of a murderer. Join me as we sniff out serial killers on today’s FYI.  My special guest on this show is author, reporter, criminologist Francisco Caballero Perez. If you want EXCLUSIVE bonus audio/video content along with, weekly/monthly classes, and tons of advantages; become a Patreon member at http://patreon.com/albertoalonsoSupport the show (https://www.patreon.com/albertoalonso)
