How big was Trayvon Martin?

I'm seeing all sorts of people claiming Trayvon's pictures that are being shown by the media are from years ago. I have seen some people claim he was 140lbs and I've seen others say up to 220lbs.

I need to know if anyone has a good solid source for how big this kid was. The images being shown I'm pretty certain are old, because the CLOSEST thing I can find for a source about Trayvon's size was that he was 6'3". In the same article that it is mentioned he was 6'3" it also says he was 140lbs.

Now, I don't know about anyone here, but this seems wrong to me. Was he 6'3" or 140lbs? There's no way he was both. I'm an amateur boxer and I fight at 140lbs. I am also 5'11"-6' tall. I have very rarely seen fighters at 140lbs that are over 6' tall. I can literally only think of two, ever. Keep in mind that fighters DROP weight, where as football players do not.

Something isn't adding up and it seems that there is almost NOTHING but propaganda going around, so I'm just trying to clear up the kid's size.

Anyone?

^Best source I can get that actually mentions Trayvon's size.
