One of the fiends who killed a woman and her two daughters in a heinous home invasion in Connecticut in 2007 was re-sentenced to six consecutive life terms behind bars Tuesday — but the victims’ angry kin say that’s still not enough.

Cynthia Hawke Renn, whose sister Jennifer Hawke-Petit was killed along with Jennifer’s two daughters, raged against the new sentence for Joshua Komisarjevsky. The killer and his murderous cohort, Steven Hayes, were originally given the death penalty but then re-sentenced to life behind bars when the state abolished executions.

“I feel like the death penalty was an easy way out, and life in prison certainly, in my opinion, is not bad enough,” Renn, 55, told the Post.

“I wish there were an alternative because I think that punishments should fit the crime,” Renn said. “I don’t really feel comfortable living in a world where a person can commit this caliber of a crime and still walk the earth.”

She said she feared the men would continue their crime spree in prison or break out.

“Just the fact that they’re walking the earth doesn’t allow me to rest easy,” Renn said.

On July 23, 2007, Komisarjevsky and Hayes raided the Cheshire home and raped and murdered Hawke-Petit and her 17- and 11-year-old daughters. Her husband and the girls’ dad, Dr. William Petit, was beaten with a baseball bat and tied up before escaping.

Hayes and Komisarjevsky fled but were later caught and sentenced to death by lethal injection for the killings. Then in August 2015, the state abolished the death penalty.
