Law enforcement confirmed Aaron Hernandez sent a letter to a fan declaring his innocence and even saying he will return to the NFL.
In the letter, obtained by TMZ, Hernandez said God put him in the situation for a reason, and he is already humbled by the experience.
"Can't wait to sign this [autographs] again when I'm playing again an [sic] prove all the haters WRONG," the letter stated.
Hernandez also said "the world just makes things out of false accusations and it will all die down, especially when they say not guilty."
The fan said he sent Hernandez the letter to offer encouragement after having been in the same jail before.
Hernandez even signed the letter with the number "81" in his signature, which was his uniform number with the New England Patriots, saying he can't wait to sign it when he is playing again.
Law enforcement said the letter is authentic.
Hernandez is accused in the murder of semi-pro football player Odin Lloyd. Lloyd's body was found in June not far from Hernandez's Massachusetts home.
Hernandez has entered a not guilty plea.
Day 5 of Bristol pond search turns up no weapon tied to the Hernandez case
A .45-caliber Glock used in the murder has not been located. Investigators said they received a tip that the weapon could be in Pine Lake in Bristol, which is Hernandez's hometown.
Authorities searched Pine Lake in Bristol for the fifth day in a row. The lake is noticeably cleaner because state police divers from Connecticut and Massachusetts cleared the algae-filled waters as they searched.
Nothing was located in the lake on Friday, authorities will meet during the weekend in Massachusetts to determine if the search will continue into next week.
Drivers focused on one area that was clearly marked and three people plunged in for more than an hour at a time.
Investigators said teams have not even come close to searching the entire lake as it's about 54 acres and as deep as 16 to 18 feet.
"I'm about the same age as him. I went to school with him. I don't know him; just passing him in the hallways, but it's interesting," said Aerial Russell, of Waterbury. "It's interesting to watch. I wanted to also support the police that are doing it. They're doing a good job."
The lake is less than 2 1/2 miles from the home of Hernandez's uncle on Lake Avenue, which was searched multiple times.
Two of Hernandez's associates, Ernest Wallace and Carlos Ortiz, both with Connecticut Connection, face lesser charges related to the case. Wallace and Ortiz both lived at the Lake Avenue home at one point.
"It's sad to see it happen. I feel bad for the family and the community," said Dale Grande, of Waterbury. "I feel bad for Aaron but if everything happened the way it is, he's not guilty yet but if he is, then he faces it like any other person would face it."
