A New Haven jury sentenced Joshua Komisarjevsky Friday to death for his role in the murders of Jennifer Hawke-Petit and her daughters.

Jurors deliberated for five days before reaching a decision. Deliberations took about 19 hours.

In October, the same jury convicted Komisarjevsky of killing Hawke-Petit and her daughters, Hayley, 17, and Michaela, 11 during a home invasion of the Petits' home in July 2007.

The seven women and five men of the jury could have spared Komisarjevsky's life and opted for life in prison without parole, but chose to impose a death sentence on him on all six capital felony counts.

"Justice has been served," Dr. William Petit said shortly after the verdict. "We are satisfied the defendant has been judged to be the murderer, the rapist and the criminal that he is. And now he's been condemned to the ultimate penalty."

The jury found that the defense proved that Komisarjevsky's background had an impact on the crime. However, they didn't think that outweighed the heinousness of the crimes and unanimously chose death on all counts.

"We've been criticized over the years that this has been vengeance and bloodlust, but this is justice," Petit said.

Komisarjevsky showed no reaction in the courtroom as he learned that he is heading to death row, along with his accomplice.

A different jury sentenced Komisarjevsky's co-defendant, Steven Hayes, to death last year for his role in the crimes.

Komisarjevsky's parents were not in court to hear the verdict, but his uncle and aunt were in the room when the verdict was read. They were sitting on the prosecution side with the Petit family.

Komisarjevsky's uncle, Chris Komisarjevsky released a statement just after the verdicts were read:

"From the begining, we have spoken out about the the horror of the crime and taken the position that whatever verdict the jury reached was the right verdict. With today's jury decision, our view is the same. The crime was monstrous and beyond comprehension. There are no excuses. As a family, we believe that each individual bears personal responsibility for the decisions he makes. Speaking on behalf of my family, my sister's family, and John Chamberlin's children, we are united in expressing our apologies and sorrow to the Petit and Hawke families. While their sadness will never go away, they have always shown such dignity in the face of their sorrow. And we will be eternally grateful for their kindness to us."

Chris Komisarjevsky also said that he and his family shed tears throughout the trial and shed tears Friday. He said the tears were for the Petit and Hawke families.

Formal sentencing for Komisarjevsky will happen on Jan. 27 at 10 a.m. Judge Jon Blue will take up some motions by defense and the state before then.
