This is a fascinating and disturbing story. As a youngster he was indoctrinated into Santeria by his mother, performed animal sacrifices, then went on to the darker practices of Palo Mayombe, and the drug-addled Miami nightlife scene. This sets the stage for the horrible events that follow. However, the most disturbing aspect of this show and the people interviewed, is that most firmly believe in the same superstitious nonsense that took hold of this young man. One interviewee says he thinks Constanzo had some kind of working relationship with the "devil." Which leads me to ask, is their answer to perform a "cleansing?" I find nothing reassuring at all in the official response to this horribly dark piece of Mexican criminal history. And the production values of the Biography channel cross the line into sensationalistic, superstition-inducing fear, without once contemplating the possibility of purely man-made superstitious terror, and sociopathic behavior.

That anyone could be taught to be evil and believe in this stuff is incredible. Religion in the hands of evil people is truely devastating.
