Hernandez has pleaded not guilty to murder in the death of Odin Lloyd, a 27-year-old Boston semi-professional football player whose body was found June 17 about a mile from Hernandez's home in North Attleborough, Mass. The ex-player's attorneys have called the case against him circumstantial.

The fan who wrote the letter was later identified only as Karl. When Karl first wrote Hernandez, he says he included pictures of Hernandez's fiancé and his baby girl. In the reply, Hernandez mentioned the pictures are now hanging in his cell.

According to David Portnoy from Barstoolsports.com the photograph was also shopped to him for $20,000.
