Two weeks after former NFL player Aaron Hernandez apparently killed himself inside his Massachusetts prison cell, new details have surfaced about the incident indicating that he was naked at the time and that he wrote "John 3:16" in blood on the wall of his cell.

The former member of the New England Patriot was found hanging on his cell on April 19 in an apparent suicide, according to TMZ, citing a police report.

Additional details have been released regarding the suicide, including the finding that Hernandez apparently made sure no one would come to his aid as he jammed the door of his cell with cardboards.

Officers from the Souza-Baranowski Correctional Facility found drawings written on the wall in blood with a Bible opened on the verse John 3:16 under the drawings, The Daily Mail reported.

John 3:16 is one of the key verses of Christianity, stating, "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life."

The police report did not say what the drawings were but took note that there was a blood mark on the 16th verse on chapter three of the book of John.

The former NFL player also had a cut on his middle finger and large circular marks on his feet, apparently from blood. There was also ink on his forehead.

Officials from the correctional facility saw his cell window covered with a sheet, which alerted them that something was not right.

When the authorities entered, they found shampoo all over the floor in an apparent attempt to make it slippery so that Hernandez wouldn't be able to stabilize his footing in the event that he changed his mind.

Upon further investigation, no drugs were found in the body of the ex-New England Patriots star.

Three handwritten notes were found in his cell, and experts confirmed that they were in the former NFL player's hand. The letters were addressed to his fiancée, Shayanna Jenkins, their daughter, and Kyle Kennedy, the inmate he became friends with in prison.

According to the Boston Globe, the note addressed to Jenkins told her that his death was the "Almighty's plan".

"Shay, you have always been my soul-mate, and I want you to live life and know I'm always with you," he said. "I told you what was coming indirectly!  I love you so much and know you are an angel - eternally!"

He added: "This was the Supreme's, the Almighty's plan, not mine!"

Hernandez purportedly committed suicide five days after he was acquitted from the double killings of Daniel de Abreu and Safiro Furtado in 2012.
