New Haven, Connecticut (CNN) -- Connecticut jurors recessed Saturday without deciding the sentence of Steven Hayes, who was convicted of killing two sisters and their mother during a brutal 2007 home invasion. He faces life in prison or death.
Judge Jon Blue ordered the five men and seven women on the jury to resume their work at 10 a.m. Sunday. Total deliberation time in the sentencing phase of the trial now stands at around 11 hours.
Earlier Saturday, the jury sent a note requesting a read-back of some of the testimony of Dr. Eric Goldsmith, a psychiatrist who had said Hayes was significantly impaired at the time of the crimes and experienced an extreme emotional rage. Goldsmith was a witness for the defense.
Friday, the jury asked Blue for clarification of the statute regarding mitigating factors -- evidence presented that would provide a reason for a sentence less than death. "How do we fill out the form?" the jurors asked.
Blue instructed the panel members that they could not go into the second phase -- determining whether the prosecution has proven the aggravating factors -- until they were unanimous about whether there were mitigating factors.
Thursday, Hayes' lawyer told jurors his client would suffer more if given a life sentence.
"Life in prison without the possibility of release is the harshest penalty," said Tom Ullmann. "It is a fate worse than death."
Ullmann then had his 47-year-old client stand directly in front of the jury. He put his hand on Hayes' shoulder and said to the jurors, "He isn't a rabid dog that needs to be put to death. He has lost 80 pounds. He will never have a private bath. He goes to the bathroom in public. He will never eat a dinner that he makes, but one that they provide. He has a rec cage for an hour a day. Like an animal at the zoo."
As he stood, Hayes -- who did not testify during the trial -- looked down at the floor.
His lawyer continued, "If you want to end his misery, put him to death. ... If you want him to suffer and carry that burden forever, the guilt, shame and humiliation, sentence him to life without the possibility of release."
But prosecuting attorney Michael Dearington sought to persuade the jurors to order Hayes be executed for his role in in the deaths of Jennifer Hawke-Petit, 48, and her daughters, 17-year-old Hayley Petit and 11-year-old Michaela Petit.
"We cannot tie Steven Hayes to a bed, pour gasoline on him and set him on fire," Dearington said, referring to the killings. "But under our laws, we do have the death penalty."
He added that the Petit family had been "destroyed because Steven Hayes wanted money."
A psychiatrist testified last month that Hayes had told him, "I would rather they kill me," reflecting Hayes' apparent hope that he'd be executed.
The high school dropout said he had a long history of substance abuse, the psychiatrist said.
But Dearington said Thursday that that did not excuse the murders. "Drugs don't necessarily lead to violent crimes," he said.
Hayes was convicted last month of 16 of the 17 charges against him, including nine counts of murder and capital murder and four counts of kidnapping.
Prosecutors allege that Hayes and Joshua Komisarjevsky invaded the Petit home in Cheshire, Connecticut; beat Dr. William Petit; raped and strangled his wife, Hawke-Petit; sexually molested one of their daughters; set the house afire; and tried to flee.
The girls died of smoke inhalation; Petit himself escaped to a neighbor's home.
Komisarjevsky is to be tried separately.
