was the son of sam the zodiac killer
Son of Sam & the similarities to Z. We all know that the 'Son of Sam' is officially recognized as being David Berkowitz. The similarities between both cases could be nothing more than simple coincidence, and i'm not suggesting that this is evidence of any connection. 1. The N.Y killer called himself the Son of 'Sam' and claimed to have headaches. A 'Sam', suffering headaches, also shows up in Zodiac Case. 2. Zodiac often shot young couple's in vehicles. Son of Sam also had this MO. Both also enjoyed writing to press and goading police.
