Convicted triple murder Joshua Komisarjevsky has broken his silence on death row and talked for the first time since he was sentenced in January for Connecticut’s most horrific home invasion.

In an interview with the Associated Press, the killer revealed that there isn’t anything he could say to Dr. William Petit that "will restore the lives lost."

As a judge decides whether convicted triple murderer Joshua Komisarjevsky's nine-year-old daughter should testify in the death penalty phase of his trial, RadarOnline.com can exclusively reveal that he was considered a caring parent right up to the night before the killings.

Caroline Mesel was Komisarjevsky's girlfriend at the time of the July 23, 2007 home invasion in Cheshire, Connecticut and has now exclusively opened up to RadarOnline.com about her experiences dating the single father.

As RadarOnline.com previously reported, Komisarjevsky was found guilty of 17 counts on October 13 for the grisly murders of Jennifer Hawke-Petit and her daughters, Hayley, 17, and Michaela, 11, and the vicious beating of their father, Dr. William Petit, but the cold-hearted killer had a different side to him.

The testimony in the Petit Family murder trial was as grisly as ever on Thursday but this time the acts of torture and sex abuse had been inflicted on triple murder suspect Joshua Komisarjevsky, not by him, RadarOnline.com has learned.

When the defense took the stand for their second day in the New Haven, Connecticut courtroom, the testimony was again from New York University  psychologist Dr. Leo Shea, who told jurors how as a 14-year-old the accused killer had carved the word "hate" on his arm because he found self-mutilation "soothing," reported the Hartford Courant.

As RadarOnline.com previously reported, Komisarjevsky is the second suspect to stand trial in Connecticut's most horrific murder and has been on trial since September 19, charged with 17 counts including murder, abduction and assault in the triple homicide of a mother and her two children, and the beating of their father.

With the prosecution in the Petit family murder trial resting their case on Monday, it was the turn of the defense team for Joshua Komisarjesky to take the stand in the New Haven, Connecticut court room on Wednesday, RadarOnline.com can report.

In a desperate bid to prevent the accused triple murderer from joining his accomplice on death row, Komisarjesky's attorneys first focused their attention on his sidekick, Steven Hayes, and his behavior in the days and weeks before the 2007 killings of Jennifer Hawke-Petit and her daughters, Hayley, 17, and Michaela,11, reported the Hartford Courant.

Despite the defendant's chilling confession earlier in the trial that detailed how he beat Dr. William Petit, the sole survivor in the horrific attack, on the head with a baseball bat and then sexually assaulted his 11-year-old daughter while she was tied to a bed, his attorneys are arguing that their client only intended to break in and steal the family's belongings, not to kill them.

After ten days of shocking evidence and disturbingly graphic details, the prosecution in the death penalty trial of Joshua Komisarjevsky rested it's case on Monday, RadarOnline.com has learned.

Since September 19, jurors in the New Haven, Connecticut courtroom have heard testimony from over 30 witnesses in the horrific case against the alleged killer, who is charged with 17 counts including murder, abduction and assault in the triple homicide of a mother and her two children, and the beating of their father.

The grisly case revolves around the seven-hour abduction of Dr. William Petit, his wife Jennifer Hawke-Petit and their daughters Hayley, 17, and Michaela, 11, who were held hostage in their Cheshire home on July 22, 2007.

The death penalty trial of triple murderer Joshua Komisarjevsky was delayed once again on Monday morning when his defense attorney appealed to the judge yet again for a mistrial, RadarOnline.com has learned.

The latest request by Komisarjevsky's legal team came after it was revealed  that a jury member had been approached by a supporter of the Petit family last week, reported the Hartford Courant.

Superior Court Judge Jon C. Blue of the New Haven, Connecticut court denied the motion but warned spectators not to speak to the jury.

Following the early exit from the courtroom of Dr. William Petit and other family members the day before, the defense attorney for triple murder suspect Joshua Komisarjevsky unsuccessfully asked the judge for a mistrial on Thursday, RadarOnline.com has learned.

The request was made by Jeremiah Donovan on the grounds that the commotion caused by the Petit family’s exit was prejudicial to his client, but was rejected by Judge Jon C. Blue, reported the Hartford Courant.

"They left en masse. It seems to be that is so prejudicial to my client," said Donovan, who asked the judge to prohibit Petit family members from pulling "any stunts like that again."

Just when you think the evidence in Joshua Komisarjevsky's death penalty trial for his part in the Petit family murders couldn't get any worse, it took another grisly turn on Wednesday.

Just minutes after the state's chief medical examiner Dr. H. Wayne Carver took the stand to testify, grieving father and husband Dr. William Petit and more than a dozen other distraught family members left the courtroom, reported the Hartford Courant.

As RadarOnline.com has previously reported, Komisarjevsky is charged with 17 counts including murder, abduction and assault in the triple homicide of a mother and her two children, and the beating of their father.

The horror surrounding the Petit family murders was taken to new extremes on Wednesday as jurors viewed graphic photos of one of the young victims, 11-year-old Michaela, on the suspect's cellphone, RadarOnline.com has learned.

The disturbing images of the girl, who was one of the three victims in the 2007 home invasion that escalated into Connecticut's most shocking murder, were taken by accused killer Joshua Komisarjevsky, the second suspect to stand trial for the grisly crimes.

As RadarOnline.com previously reported, 31-year-old Komisarjevsky is charged with 17 counts including murder, abduction and assault in the triple homicide of a mother and her two children, and the beating of their father.

In disturbing and calculated detail, death row murder suspect Joshua Komisarjevsky explained to police how a home invasion escalated into a triple murder, and RadarOnline.com has the chilling audio of the interview.

During the taped confession, which was released on Monday, the accused killer spoke in a monotone voice and barely paused or stumbled as he described the horrific events after he and accomplice Steven Hayes broke into the Petit family home in Connecticut.

As RadarOnline.com previously reported, Komisarjevsky - the second suspect in the most horrific murder in Connecticut history - is charged with 17 counts including murder, abduction and assault in the triple homicide of a mother and her two children, and the beating of their father.
