Although Hernandez didn't leave behind any type of letter, it appears that he did take a marker and write something on his own body prior to his death.
Last Friday, Hernandez was acquitted of murdering Daniel de Abreu and Safiro Furtado in a July 16, 2012 shooting.
"I'm not happy about his death", de Abreu said.
However, it's hard to portray Hernandez as a tragic figure, considering how much misery he inflicted on others, especially the Lloyd family, and those of de Abreu and Furtado, whom prosecutors still believe Hernandez killed.
Witnesses at Hernandez's two murder trials painted a picture of a troubled man who often used illegal narcotics and at times believed strangers were challenging or disrespecting him. "We got a commitment from the Patriots that before any of that payment would be made they would notify the court to give us a chance to deal with that". As a result, Hernandez could be legally cleared. Just days after Hernandez was acquitted in a separate murder case, his friends, family and his legal team were searching for an explanation.
"It will turn on a question of the interpretation of the player's contract as well as the contract with the Patriots as to whether or not that money is in fact due to him", Massachusetts School of Law Dean Michael Coyne said.
Removing a conviction after the death of a high profile defendant has happened before in recent history.
Former Roman Catholic priest John Geoghan's child molestation conviction was vacated after he was beaten to death in his prison cell in 2003.
MA state police has launched an investigation into the circumstances around Hernandez's death.
"There were no conversations or correspondence from Aaron to his family or legal team that would have indicated anything like this was possible", said his attorney, Jose Baez.
The Worcester County district attorney's office and the Correction Department are investigating.
Hernandez grew up in Bristol, Connecticut, and played for the Patriots from 2010 to 2012.
But the Patriots released him in 2013, shortly after he was arrested in the killing of semi-pro football player Odin Lloyd, who was dating the sister of Hernandez's fiancee. Otherwise, he would have been transferred to a mental health unit, Fallon said.
"So he was acquitted, but two days later is Easter Sunday and he's in the same spot he was in before, so maybe for him the weight of that was too much to take".
Hernandez's former agent, Brian Murphy, said on Twitter that he did not believe the athlete had killed himself.
An official with the Massachusetts Department of Corrections says Hernandez was found hanged in his cell just after 3 a.m. Wednesday. MA prison officials said Hernandez hanged him.
Convicted murderer and former National Football League star Aaron Hernandez was found hanged in his MA prison cell Wednesday morning, officials said, just days after his acquittal in a double murder case.
"Lifesaving techniques were attempted on Mr. Hernandez and he was transported to UMASS Leominster where he was pronounced dead at 4:07 a.m.by a physician at the hospital", assistant-deputy commissioner of communications Christopher Fallon said in a statement.
