NEW HAVEN, Conn. (CNN) - One of two men convicted in the rape and murder of a Connecticut family says it took him more than a year to remember what happened.
More than six years ago, Steven Hayes and his accomplice broke into a house in Cheshire, Conn., taking a family of four hostage. Only one member of the Petit family survived.
Speaking from prison to a Connecticut newspaper, Hayes says he "just snapped." He says, for a few minutes, he became someone else.
Hayes and Joshua Komisarjevsky forced 48-year-old Jessica Hawke-Petit to go to a bank and take out $15,000. They then returned to her home, where she was raped and strangled.
Her husband, William Petit, escaped from the basement, but Hayes and Komisarjevsky tied the couple's two daughters to their beds and set the house on fire, killing the 11 and 17-year-old girls. The younger girl was also molested.
In Hayes' hour-long interview with the New Haven Register, he apologized, expressing feelings of "guilt, shame, and remorse." He says he didn't know what he was thinking, and he says he'll never forgive himself for what he did.
He and Komisarjevsky were both tried, convicted, and sentenced to death for their actions in the 2007 home invasion.
