What Cleared Giovanni Ramirez in the Brian Stow Case

With new arrests in the Brian Stow beating case, the media is taking a look at what appears to have helped exculpate Giovanni Ramirez, who was initially picked as a suspect.  Ramirez had tattoos that were similar to those reported by eyewitnesses, but good investigation helped paint a fuller picture suggesting that he could not have been the assailant.  SFGate reports:

Ramirez’s lawyers . . .  insisted their client was innocent. They said they found surveillance video at a Denny’s restaurant showing he had hair the day witnesses described seeing two men with shaved heads beating Stow. Ramirez submitted to two lie detector tests, provided nearly a dozen alibis and cellphone records to show where he was when he made calls around the time of the attack.
