JOLIET – 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 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.
