::I'm having trouble getting over "perhaps because of." It still reads like WP:OR, as to me "perhaps" seems like "maybe" with respect to contemplating or hypothesizing. And although its not specifically on the list for WP:WTW, lets remember that guideline "...is not limited to the examples..." That being said, I found the use of that phrase in well over 500 articles, with many being GA quality, so I will not let that cloud my opinion on the GA nature of this article.  
 ::I also don't like mentioning that he was shot, then explaining why 3-4 sentences later. You may want to "draw the reader in" which would be great for a novel or newspaper article, but we are an encyclopedia first. That being said, I also won't let this affect the overall opinion.  
 ::With the changes that you have made, I believe the quality of this article is much improved and I am happy to promote this article to Good Article. Cheers, ''''''''''
