Prosecutors may have more evidence to prove that Aaron Hernandez has had a violent past, as a police report shows that Hernandez was involved in an incident with a man in May 2007.According to the police report, on May 4, 2007, Hernandez, then 17-year-old, punched a man in the side of his head in Gainesville, FL, which resulted in the man's eardrum to rupture. The police report goes on to say that when asked by police what happen, Hernandez never disputed the fact that he punched the man in the head. The incident took place months before Hernandez had enrolled at the University of Florida. The police report details that Hernandez was served two "alcoholic drinks" at a restaurant near the school campus called The Swamp. When Hernandez finished the drinks, a male employee delivered Hernandez the bill, but Hernandez insisted that he hadn't ordered any drinks, so he refused to pay. The two men got into a 'verbal altercation' that resulted in the employee escorting Hernandez out of the restaurant.Once outside, Hernandez alleges that the employee got in the face, according to the police report. As the employee turned to walk away from Hernandez, he punched the employee in the side of the head. Even though police recorded the incident in the their report, Hernandez wasn't arrested. A Gainesville Police Department spokesman says that even though Hernandez wasn't charged, the department recommended a charge of felony battery - a crime which carries a five year sentence in prison for adults in Florida.
