Former NFL star Aaron Hernandez used his own blood to draw "odd symbols" on his prison wall before committing suicide, a new report claimed Saturday. The 27-year-old, who was jailed for life without parole for the 2013 murder of Odin Lloyd, was found hanging from his prison cell window April 19 at the Souza-Baranowski Correctional Center in Shirley, Massachusetts.

According to WCVB-TV, which had earlier claimed that Hernandez wrote "John 3:16" on his forehead with ink before he died, the American football tight end wrote "Illuminati" in block letters on the wall along with an unfinished pyramid and the all-seeing eye of God, similar to the illustration on the back of the one dollar bill. Another symbol he reportedly drew was an oval with rays coming from its edges.

On Saturday, toxicology report for Hernandez revealed no traces of “K2,” or synthetic marijuana — or any other illegal drugs — in his system, Boston TV station WCVB. The report also added that correction officers found K2 and several homemade weapons during the prison search.

Hernandez's suicide, which came just days after he was acquitted in a double murder case, remains a mystery as the jailed NFL player left no suicide note. However, reports surfaced that Hernandez wrote three letters — one to his fiancée Shayanna Jenkins, another to his daughter Avielle and the last to his attorney Jose Baez. Earlier rumors claimed that his last letter was meant for his gay lover.

After rumors surfaced that Hernandez had a homosexual relationship with one of the inmates, his attorney Baez slammed officials associated with the case for leaking information to "tarnish" the ex-New England Patriots star’s reputation.

“Rumors of letters to a gay lover, in or out of prison, are false,” Baez said in a statement, cited by NBC Sports’ Pro Football Talk. “These are malicious leaks used to tarnish someone who is dead. . . . Notwithstanding my unambiguous statement that there were no such letters, representatives, on behalf of an individual named Kyle Kennedy, continues to advise the media such a gay love letter exists. Accordingly, on behalf of the family of Aaron Hernandez, I am reaffirming, unequivocally, no such letter to Mr. Kennedy, or any other individual, in or out of prison, exists. I urge anyone continuing to spread these malicious untruths to cease immediately.”

Meanwhile, Hernandez's family is demanding that the officials who leaked information about his death be fired.

“Individuals within the government who are leaking such information are in violation of the policies and procedures of their respective agencies and should be immediately terminated,” attorney George Leontire, the family’s representative, wrote to Worcester district attorney’s office and the state Department of Correction, Boston Globe reported. “Although most of the leaked information is false, the media credits such information because the leaks come from individuals with positions in government and law enforcement who are under your control.”

Amid the ongoing investigation into Hernandez's death, his fiancée Jenkins and his lawyer filed an affidavit in probate court stating that his estate is worth “$0.00” with “no monies available and no identifiable personal assets.” However, they received an offer for their mini-Massachusetts home.
