Hernandez's death comes on the same day that President Donald Trump will host his former team the Patriots - which won the premier American football championship, the Superbowl, in early February - at the White House.
UPDATE 10:31 A.M. EST: Aaron Hernandez's attorney Jose Baez claims the former pro athlete showed no signs of being suicidal!
The former Patriots tight end was still serving a life sentence for his 2015 conviction for murdering his friend Odin Lloyd in 2013. At 3 a.m. ET, prison officials discovered Hernandez hanging by a bed sheet attached to the window in his cell, in which he was the only occupant.
Just last week, Hernandez was acquitted of murder charges in the shooting deaths of two men in July 2012.
Hernandez's body was turned over to the state medical examiner's office, reports CBS Boston.
"For all intent and practical purposes, Aaron Hernandez will die an innocent man, but the court of public opinion may think differently", said Healy.
The former Patriot was the 27th recorded suicide in MA state prisons since 2010 and the second one this year, according to state records.
"Absolutely no chance he took his own life", agent Brian Murphy said on Twitter, per the Herald.
Hernandez, 27, was a rising star in the National Football League when he was arrested in June 2013 and accused of murdering an acquaintance near his MA home. "Chico was not a saint, but my family and I loved him and he would never take his own life", Murphy said, via ESPN.
The attorney who represented Aaron Hernandez in his double-murder trial is requesting that authorities investigate his former client's sudden death.
"There was no indication that he was going to do this, as far as I knew, other than such a situation would always put someone at risk", a source close to Hernandez told Radar. Prosecutors said he gunned them down after one of them accidentally spilled a drink on him in a Boston nightclub. The team released him in 2013 after he was arrested for killing Lloyd. The judge sentenced him to an additional four to five years in prison, separate from his life sentence, for that conviction.
