Hayes is convicted of raping and strangling Hawke-Petit and accused accomplice Komisarjevsky is charged with sexually assaulting 11-year-old Michaela Petit. Michaela and her older sister Hayley, 17, died after they were tied to their beds, doused with gasoline and the house was set on fire. Last month, the jury unanimously found the death penalty the appropriate punishment for Hayes' role in the triple murders.
Hawke-Renn said that Hayes will die a "peaceful" death when he's given a lethal injection, "one without pain."
"I would have given anything for my loved ones to have died in this same peaceful manner," she said.
William Petit Sr., the father of Dr. William Petit Jr., the husband and father of the victims who was badly beaten with a bat, was the only person to survive the attack on his Cheshire, Conn., home, said in his statement that his family "will never be the same."
"You destroyed our family," said Petit Sr., breaking down into tears. "[Dr. Petit] will never walk them down the aisle, he will never know the wonderment of grandchildren."
"He doubts if he should be living at all. We have lost the [Dr. Petit] we all knew," he said. "He puts on a brave face. It works for a while but there is no way of forgetting the brutal truth."
Johanna Petit-Chapman, Dr. Petit's sister, spoke about the last night she spent with her sister-in-law and nieces.
"They went to sleep on a Sunday night, they had dinner together, talked and read the new Harry Potter book," she said. "None of us would know it would be their last night."
"Three beautiful lives taken because of Stephen Hayes' selfish act," said Petit-Chapman, through tears. "He does not deserve life."
During the six-week trial that culminated in Hayes' conviction, prosecutors argues that Hayes and Komisarjevsky ambushed the Petit family on a summer night after following Hawke-Petit and Michaela home from a grocery store and targeted the family as wealthy.
The two intended to rob the family, but after finding little cash in the house they held the family captive for hours before driving Hawke-Petit to the bank to withdraw $15,000. Hawke-Petit was seen on the bank's surveillance system pleading with the teller to help her family.
Prosecutors alleged that Komisarjevsky raped Michaela, later forcing her to take a shower before tying her to her bed. During Hayes' trial, prosecutors argued that he raped Hawke-Petit before strangling her. As the two girls lay tied to their beds with Hawke-Petit dead on the lower floor of the house, Hayes and Komisarjevsky set fire to the house, prosecutors said, pouring gasoline on and around the girls' bed before fleeing.
Komisarjevsky, 30, is scheduled to stand trial early next year.
Hayes will join nine other men who currently await execution on Connecticut's death row, which is housed in the Northern Correctional Institution in Somers, Conn.
The last inmate to be executed in Connecticut was serial killer Michael Ross in 2005.
Hayes' lawyers had argued that he should be spared execution because the ringleader was Komisarjevsky who escalated the violence instead of carrying out a house robbery as originally planned. The lawyers also argued that Hayes had expressed remorse for the crime and wanted to be executed.
