JOLIET, Ill. — A suburban Chicago man was sentenced to life in prison Tuesday for killing his wife and three school-age children as they sat buckled into the family’s SUV, allegedly so he could start a new life subsisting in the Canadian wilderness.
The sentencing of Christopher Vaughn, 37, came two months after jurors found him guilty of killing his 34-year-old wife, Kimberly, and their children on June 14, 2007. Each child was shot once in the chest and head.
The judge sentenced Vaughn to four consecutive life sentences with no possibility of parole. Vaughn did not make a statement in court.
Kimberly Vaughn’s twin sister, Susan Ledbetter, poignantly described her pain, telling the court how she occasionally walks by a mirror and sees her sister’s image and how she hears her sister’s laughter whenever she laughs.
‘‘I silently wonder if my parents and older sister experience pain in my presence because Kim and I share not only our looks but also many of our personality traits,’’ she said, weeping as she read her impact statement to the court.
Vaughn, who lived with his family in a spacious Oswego home, faced a mandatory life term for the killings. But the hearing in Joliet gave relatives a chance to confront him and to convey how much pain he caused.
The 2007 murders started out as a death penalty case, slowing the pace to trial. But Illinois has since abolished capital punishment, making life in prison the maximum penalty.
‘‘There isn’t a punishment that fits this crime,’’ Will County State’s Attorney James Glasgow told reporters outside the courtroom after the sentencing.
‘‘What this guy did here was a diabolical atrocity, and he’s a heartless, soulless, psychopath,’’ Glasgow said.
