Aaron Hernandez's red flag

Former New England Patriots football player Aaron Hernandez was found guilty of first-degree murder. This is a sudden fall from grace for the star tight end who held a prized contract worth $40 million. How did jurors reach this conclusion? They heard hours of testimony from dozens of people. But one witness's testimony stood out. And, surprisingly, it wasn't from a witness who was even with Aaron Hernandez the night of the murder. Who delivered some of the most memorable testimony? It was the Patriots owner, Robert Kraft.
