Hernandez’s defence lawyer Jose Baez issued a statement saying there was no previous indication the former football player would take his own life.

“The family and legal team is shocked and surprised at the news of Aaron’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,” Baez said. “Aaron was looking forward to an opportunity for a second chance to prove his innocence. Those who love and care about him are heartbroken and determined to find the truth surrounding his untimely death.”

The attorney is calling for a “transparent and thorough investigation” into the death of his client.

Hernandez was acquitted Friday in the 2012 double murder that prosecutors said was fuelled by his anger over a spilled drink.

The jury found Hernandez not guilty of first-degree murder in the killings of Daniel de Abreu and Safiro Furtado. It convicted him of a single charge: unlawful possession of gun. The judge sentenced him to an additional four to five years in prison, separate from his life sentence, for that conviction.

As the Associated Press reported, prosecutors accused Hernandez of opening fire on their car because he felt disrespected when one of the men bumped into him and spilled his drink at a Boston nightclub.

Hernandez grew up in Bristol, Connecticut, and played for the Patriots from 2010 to 2012. About six weeks after Furtado and de Abreu were killed, Hernandez signed a five-year, $40 million contract with the Patriots and went on to play another season before Lloyd was killed. He was cut from the team shortly after he was arrested in Lloyd’s killing in June 2013. He was not charged in the 2012 killings until 2014.
