A Connecticut jury has found Joshua Komisarjevsky guilty of helping murder
Dr. William Petit's wife and two daughters in 2007.
Komisarjevsky, 31, now has a penalty hearing on whether he will join his accomplice Steven Hayes – who was convicted of 16 charges, including murder, last year – on death row.
Petit family members wept as the verdict was announced after nine hours of deliberation. Komisarjevsky was convicted on a litany of charges including murder, kidnapping, arson, burglary and assault in the brutal deaths
of Jennifer Hawke-Petit, 48, Hayley Petit, 17, and Michaela Petit, 11.
Jennifer was strangled to death while Hayley and Michaela were set on fire. The defendants confessed, but they pleaded not guilty.
William Petit called the verdict "a relief," describing Komisarjevsky as "a lying sociopathic personality."
Appearing somber before reporters in front of the New Haven courthouse, Petit said there are only "occasional moments of peace."
"It's not clear to me that time heals all wounds," he says, "but you form some scars."
