When Aaron Hernandez was found dead in his prison cell on April 19, 2017, his fiancée, Shayanna Jenkins-Hernandez, says she was shocked and thought it was a hoax. It is reported that Hernandez committed suicide, but Jenkins-Hernandez says she doesn’t believe he took his own life and says she wants answers from the prison.

There were three handwritten notes investigators say they found next to a Bible in Hernandez’s cell at the Souza-Baranowski Correctional Center in Massachusetts, one addressed to Jenkins-Hernandez.

In an exclusive interview with Dr. Phil, Jenkins-Hernandez speaks out for the first time since her high school sweetheart's death and shares what she thought was odd about the note he left for her.

“I did see that it was addressed to Shay instead of Babe or Bae, the way he would refer [to] me as that, was a little odd to me,” she tells Dr. Phil in the video above from Monday’s episode. “But as far as the content seemed to be his loving self.”

Jenkins-Hernandez says he was positive and excited to come home, and that's why she says she has doubts that he took his own life.
