On the first of our three part series, we cover one of the most successful hitmen (serial killers?) of our age: Richard Kuklinski. Join us as we discuss his terrible upbringing, his early years as the head of the Coming Up Roses gang, and the possibly dozens of men he murdered in New York City in the fifties just for the practice.    Save 30% on your 23andMe Health + Ancestry service kit through August 9th at http://23andme.com/left
