A couple of ?s...
I've heard a couple of people say we can't trust Gracie's account of things b/c the long-time customer who also witnessed the exchange never came forward. Wasn't it testified that that person died?
Also... was Mr. G outside when MF found MY? TIA. Trying not to obsess. Not succeeding.
I think she added new information during the second trial that the other customer was a newspaper delivery guy ... that person has since passed away. Police had surveillance video in the store for 60 days after the murder but didn't bother to review it with the gas attendant. It would have strengthened the prosecution's case if that other customer - the one that supposedly yelled out to Jason - had been located. If that other customer had been identified and said that he didn't recognize Jason, that would have discredited the prosecution's theory ... so one does have to question why police didn't try harder to identify the other customer.
Mr G was inside and going nuts IIRC.
