Aaron Hernandez throwing up a gang sign (Photo)

TMZ has obtained a photo of former Patriots tight end Aaron Hernandez throwing up a gang sign when he was 17 years-old and a senior Bristol’s Central High School.  The sign that he’s throwing up is allegedly from the Bristol Bloods street gang in Bristol, Connecticut.

If you also look at Hernandez’s hand from yesterday’s arraignment, the word “blood” is tattooed on it.  It seems like everything is adding up to his life as a gang member.
