Attorneys for the Hernandez family are conducting their own investigation into his death at the Souza-Baranowski Correctional Center in Lancaster, Massachusetts.
The first part of a two-part interview with Shayanna Jenkins-Hernandez aired Monday on the Dr. Phil show.
"I did see that [one suicide note] was addressed to "Shay" instead of "Babe" or 'Bae, ' the way he would refer [to] me as that, was a little odd to me", Jenkins-Hernandez said.
She said she thought the news of Hernandez's death was a "hoax" and some cruel person was playing a trick on her.
"Not to my knowledge", Jenkins-Hernandez responded.
"I don't know what to believe, to be honest with you".
Jenkins-Hernandez said she was suspicious of the state's conclusion that Hernandez killed himself.
"When Dr. Phil asked if the handwriting on the note belonged to Hernandez, Jenkins said, "(It) was similar, but I feel like, again, you have nothing but time in there so I feel like it's easily duplicated or could be.
Following a MA formality, a judge vacated Hernandez's conviction in the Lloyd case after the onetime superstar's death, but a prosecutor promised to appeal the decision.
She repeated comments she made on the stand during his murder trial in the death of Lloyd, telling McGraw she would "pick and choose her battles" with Hernandez.
Kohli terms IPL 10 as a season to forget for RCB
Prior to the start of the season, no one could have imagined that RCB would be the first team to be eliminated from the contest. They made a slow start, scoring 37/1 at the end of Powerplay overs (six), with Gayle contributing 32 runs off 24 deliveries.
Jenkins-Hernandez unequivocally stated that if she'd known or even suspected that Aaron Hernandez was contemplating suicide, she would have done whatever she need to do to get him the help he needed.
In a phone call to his fiancee only hours before he died, Aaron Hernandez gave no indications he was going to kill himself and ended the call by telling Shayanna Jenkins Hernandez "babe I gotta go, they are shutting the doors".
Aaron Hernandez's fiancee went on to discuss his alleged suicide with Dr. Phil, making it clear that she doesn't believe that he took his own life.
"He may have been at the wrong place, wrong time", she said.
As Radar reported, Hernandez was found hanging in his jail cell the morning of April 19.
Although a state police investigation closed the matter, the late National Football League player's fiancée said, "I don't think this was a suicide", telling Dr. Phil the findings are not believable to her and that she is calling for an inquiry.
The conversation turns to the couple's 4-year daughter, Avielle Janelle Jenkins-Hernandez. "It wasn't intimate", she said.
She said he also didn't sign the note "your soul mate", which she said he usually did. "I wanted more. I wanted him to explain", she said.
She added: "It screamed love, but it wasn't personal".
