Tyler Hadley, who killed his parents in 2011, talked about his resentencing hearing, how he's "adjusting well" in prison and how he thinks about what could have been different during an Aug. 14 interview with forensic neuropsychologist Dr. Dan Martell.

Hadley, now 24, was 17 when he used a claw hammer to bludgeon his parents to death in their Port St. Lucie home: mother Mary Jo, 47, and father Blake, 54.

"I really don't want to go through it again, but I have to," Hadley said during the hours-long interview, referring to this week's resentencing hearing.

"It's hard to face, really. ... I got to put my family through this again," he said. "Then I got to sit there and, and rehash everything again, and it's just ... it's really hard facing the other side of my family because I know at least two of them are going to be there."

Blake's side of the family wants Tyler to spend the rest of his life in prison. Mike Hadley, Blake's brother and Tyler's uncle, urged the judge this week to reimpose that sentence. He came to court with his wife, Cindy, and his father, Maurice Hadley.

Other testimony during this week's hearing included:

Things could have been different

During the clinical interview, Hadley said things could have been different.

"I'm just thinking about, like, things that, you know, I could have done different," he said. "I should have just went to school ... it's just little things ... like, OK, if you would have done that, you know, things would have been different."

In 2014, Hadley pleaded no contest to two counts of first-degree murder with a weapon and was sentenced to two life prison terms. An appeal he won threw out his life terms and sent the case back to Circuit Judge Gary Sweet to impose a new sentence.

Hadley faces anywhere from a minimum of 40 years to a maximum of life. It could be weeks or months after the hearing before Sweet issues his order.
