Zeyad has more on the death of his cousin and the role that the US Army played in it. I don't know what to make of this. To me, the dead man's family sounds odd. I really hope this is concocted nonsense or that the cousin was up to no good, but that his family cannot accept this.
Still, I also acknowledge that everything written here was originally in a language I don't speak and I'm not familiar with the culture at all so my judgment of what's "odd" may be off.
