Aaron Hernandez -- He's a Disgrace to Our City ... Says Mayor of Bristol

Aaron Hernandez isn't just a murderer -- he's a stain on the city of Bristol ... so says the mayor.

We spoke with Mayor Kenneth B. Cockayne ... who tells us the entire community is disgusted with Hernandez, who grew up in Bristol.

"He was a role model for the kids and adults of Bristol -- and now the hearts of those children are crushed."

"We're sick of this case, and I'm glad it's over. It puts a bad light on our whole town. He shed a lot of bad light on all of us."
