Former New England Patriots player Aaron Hernandez is still claiming his innocence as he sits in a Massachusetts jail awaiting trial for murder.In a recent jailhouse letter he wrote to a fan and obtained by TMZ, the former NFL star said he is eager to prove that he’s not guilty and make a return to the sport he loves.In the letter to the pen pal, Hernandez writes, “I know everything happens for a reason and I know ‘GOD’ has a plan for me and something good will come out of this. The world just makes things out of false accusations and it will all die down, especially when they say NOT Guilty and all the people who turned on me will feel like crap.”Hernandez also writes, “I know there is a reason Im going thru this and I will figure it out through my relationship with the Lord. I fell off especially after making all that money but when it’s all said and done ‘GOD’ put me in the situation for a reason!”Hernandez recently pleaded not guilty in the murder of Odin Lloyd, a 27-year-old, who allegedly had ties to the ex-football player. The young man’s body was found June 17 about a mile from Hernandez’s home in North Attleborough, Mass.The former NFL player ends the letter optimistic about his athletic future saying, “Can’t wait to sign this again when I’m playing again and prove all the haters and down-talkers WRONG,” Hernandez reportedly wrote following his signature.
