Friendly, regular family guy Altemio Sanchez - affectionately known around his neighborhood in suburban Buffalo, NY as "Uncle Al" - couldn't have been more of your basic solid citizen.  A wife, kids, a good job at a local factory for more than two decades - all the markings of the Friend Next Door.  Until he wasn't.  Until he used his mornings off to attack, rape and murder unsuspecting women throughout  the Buffalo area.  With a string of assaults and murders stretching from 1990 to 2006 - and possibly going as far back as 1981 - Sanchez' capture and prosecution in 2007 remains one of law enforcement's most important successes.  But the road to the killer's capture was fraught with miscues and outright bungles - and Melissa takes us through all the twists and turns of the investigation, arrest and conviction.
