Aaron Hernandez, the NFL player currently facing a murder charge, apparently wrote a letter to a pen pal from jail in which he says he's innocent. TMZ grabbed the correspondance, which they say they've verified with law enforcement officials. While the letter basically lays out Hernandez's personal defense, it closes with an indication that he didn't want it to become public: "Keep this off social media PLEASE!" 

TMZ has a watermark-laden image of the original letter here for your perusal. The text, which is apparently in response to a previous letter from a supporter, reads: 

Your letter meant alot and was very true! 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.

I've always been a great person and known for having an amazing heart! I am a strong person and nothing will break me! A C.O. will never nor can they say now for one day have I been down or not with a smile on my face. I know there is a reason I'm 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! I'm humbled by this ALREADY and this will change me forever. At least I'll know my true supporters. Thanks for being one of them!

P.S. The pictures are definitely hanging on my walls and def meant a lot! Thanks again brotha!

Thanks,

Prosecutors are building a grand jury case against Hernandez related to a double murder in 2012, or one full football season ago. He's already facing a murder charge and five gun charges for the death of Odin Lloyd. Police haven't yet found the weapon used in that homicide, but authorities have released photos of Hernandez holding what appears to be a gun soon after the slaying
