I was under the impression that he played football in middle school only, but I could be wrong. He was born on February 5, 1995 so he was just 3 weeks out of being 16-years old.
That causes me to then doubt it is he in the photo on the left. That person looks to be in the twenties or possibly early thirties.
Now, again I ask why you posted the side-by-side? Are you conjecturing that the two are not the same person or that they are of different age same person? ... Either way, this is a tragic story of a good looking young man with a life ahead of him of uncertainty due to his drug use and growing gangsta interests. But that does not eliminate the self defense nature of George Zimmerman's act.
‘just 3 weeks out of being 16’ is an odd way to refer to a person who has turned seventten. Granted, he was more a new seventeen year old than an approaching eighteen year old, but really, he was seventeen. He was also wobbly standing at the 7-11 counter and from putting data together appeared to have tried to purchase smokes, perhaps to use for a blunt, given that the three with whom he communicated outside who enetered after he walked out purchased three cigars and Martin didn’t head back toward the complex until they exited the store and truned out of the picture in his direction before he shows up heading back in the direction of the complex.
