Urban Meyer refused to take any blame for Aaron Hernandez's supposed mishandling at the University of Florida (UF), the Columbus Dispatch reported.

Since news broke of the former New England Patriots' tight end being charged with first-degree murder, many stories came forth about Hernandez's checkered past. Most have been unconfirmed or ongoing investigations, like his ties to 2012 shootings in Boston and 2007 shootings in Florida. The latter occurred when he was a freshman at UF.

Also in his freshman season was an incident where Hernandez punched a bartender in the head after teammate Tim Tebow tried to peacefully resolve the conflict. However, Meyer, the current head football coach at Ohio State University (OSU) and former UF coach, denied reports that the school and coaching staff covered up for drug testing and other incidents.

Meyer had declined to comment on those reports until Sunday in an interview with the Columbus, Ohio newspaper.

"I just received an email from a friend where there is an accusation of multiple failed drug tests by Hernandez covered up by University of Florida or the coaching staff. This is absolutely not true," Meyer texted to the Dispatch. "Hernandez was held to the same drug testing policy as every other player."

Meyer included that he had brought Hernandez to his home for Bible studies and personally tried to help him cope with his father's death in 2006.

"He was an athlete at Florida 4-7 [years] ago and there are some comments being made that are not correct," Meyer's text continued. "Our staff, myself and our families worked very hard to mentor and guide him."

Meyer also reportedly vouched for Hernandez to Patriots coach Bill Belichick on draft night in 2010 when many teams were avoiding him.

In regards to the 2007 shooting where a man resembling Hernandez and supposedly Reggie Nelson, a UF teammate, shot two men in a car leaving them wounded, Meyer said the two players were questioned as witnesses.

"One of my coaches came in and said, 'Hey, they're getting questioned for this,'" Meyer said. "I said, 'Well, what do I need to do?' And he said, 'Nothing. They're not involved.' And that was it. They weren't questioned for (doing) the shooting."

Last week, Shelley Meyer, Urban's wife, took to Twitter to defend her husband and to deflect blame from those not directly involved.

"When will we start holding individuals accountable for their own decisions/actions and stop blaming any/everyone else?" she wrote.
