MIAMI -- In another of his exclusive interviews, Rad Berky looks into the past with the anguished parents of a teen accused of murder.

Manny and Kathy Hernandez's son's arrest and the charge that he stabbed his classmate Jaime Gough to death in a middle school bathroom completely shocked them.

"We're just devastated by everything," Manny Hernandez said. "This is just pulled the rug from what we thought was the ideal life."

The Hernandezes do say before 14-year-old Michael was arrested for murder in February, they had noticed some behavioral changes -- but they couldn't tell if it was normal teenage behavior or something more.

"Typical teenage things," Kathy Hernandez said. "Listening to music that was too loud and you go to the door and tell him to turn it down."

Berky asked, "Was there anything you didn't think was typical?"

"I would say that he had gotten a lot (quieter)... He wasn't as talkative at home as he usually was with us, because he's always been a big talker," Kathy Hernandez said.

But other changes the parents noticed went beyond that to the point Manny Hernandez told state prosecutors in his deposition:

"... Around December, my wife and I would talk about the possibility of having a psychologist look at Michael."

That however, is not what the parents told Berky.

When Berky asked if they ever felt that Michael needed any help, his mother said, "No."

The parents say Michael, who had put on some weight, became consumed with exercise and diet.

Also, in her statement to prosecutors, Kathy Hernandez said Michael would stand and stare at the grandfather clock in the living room or open the doors to the refrigerator and "look side to side so many times."

His mother also said in her statement that Michael "... had something with the garage door where it had to open and close so many times."

Manny Hernandez said in his statement that on Sundays, Michael insisted on ordering a specific meal of chicken from a fast food restaurant, always at eleven o'clock in the morning: "...the same thing, every Sunday was the same thing."

And then there were the cuts the parents say they noticed on Michael's arm.

In his statement Manny Hernandez says, "... My wife says, 'What is that?' Grabbed his (Michael's) arm. Says, 'What is that?' (Michael said,) 'Oh something. I hurt myself on the fence at school.' I don't know if my wife believed that. I recall her telling him don't ever let me see that again."

Concerned that Michael was showing signs of obsessive compulsive and repetitive behavior, Manny Hernandez told investigators he talked to Michael about getting professional help. In his statement he said Michael's response was. "Well, they won't know anything if I won't tell them."

In the end, the parents decided to wait until after Michael's mid-term exams.

Now, there is no help for Michael. He is locked up in a cell.

"We're just devastated by this whole thing and that's what we would really like -- to see him get the help."

His parents say they love Michael, but speaking of him, at times in the past tense, they seemed to Berky to be longing for the boy they knew before last February third.

"He was my heart," Kathy Fernandez said. "Just my very heart."

The Hernandez family has offered their sympathy on more then one occasion to the family of Jaime Gough, a victim who they don't want forgotten in all of this.

Earlier this week, Local 10 contacted the Gough family through their attorney to let them know this series of interviews would be airing, and to allow them an opportunity to respond in anyway they saw fit. Through their attorney, the Gough's declined.
