Either way this release by the Martin/Fulton family eliminates anymore excuses for the media to show five-year-old photos so as to continue the narrative that this was a waif of a child.
What I really want to see is a video of Martin so that I can hear his voice. If it's a rather bassy one then that could easily be shown to have not been the voice heard on the 911 call screaming for help for over a minute before the gunshot (45 seconds on a 911 call recording where the caller says they were prompted by the screaming itself - so tack on at least 20 to grab a phone, call 911 and get through.)
That voice clearly sounds to me like Zimmerman at a desperate level compared to his voice on the original 911 call. If the Martin/Fulton family is so sure that is Trayvon's voice on that recording then we would have seen a video by now or heard something like a voice mail recording.
BTW - I read an older article from like the 16th where Trayvon's parents personally first heard the 911 call with the screaming and said that not only was it clearly Trayvon but that there had been TWO shots (one being a warning shot.) Now there is no evidence to support that claim and that is clear from the five calls I've heard that have witnesses stating only one shot.
