SOMERS, Conn. — A man convicted in the brutal home invasion killings of a Connecticut woman and her two daughters in 2007 said no one was supposed to get hurt.

“To this day I don't know why it happened, I just wanted money,” Steven Hayes said in a jailhouse interview.

Hayes, 50, and Joshua Komisarjevsky, 33, were convicted of capital felony, murder, sexual assault and other crimes and sentenced to death for the July 2007 killings of Jennifer Hawke-Petit and her daughters, Hayley, 17, and Michaela, 11, at their home in suburban Cheshire.

Hawke-Petit attended elementary school in Slippery Rock until her father, the Rev. Richard Hawke, moved to another church.

When Hawke retired, he and his wife, Marybelle, later returned to Slippery Rock, where they make their home today.

The two men, both convicted burglars, broke into the home. Komisarjevsky beat Dr. William Petit, the only survivor, with a baseball bat, and Hayes later went with Hawke-Petit to a bank and forced her to withdraw $15,000.

Authorities said Hayley and Michaela were tied to their beds. Komisarjevsky sexually assaulted Michaela, and Hayes strangled and sexually assaulted Hawke-Petit. The two girls died from smoke inhalation after Komisarjevsky and Hayes set the house on fire and fled before being arrested.

Hayes said he and Komisarjevsky were going to leave after he returned from the bank with Hawke-Petit. But then, he said, Komisarjevsky told him that he sexually assaulted Michaela.

“I started to lose it,” Hayes said. “Then I looked out the window and saw an unmarked police car. And I just snapped.”
