JOLIET, Ill. — An Oswego man convicted in the 2007 deaths of his wife and three children has been sentenced to four life terms in jail without the possibility of parole.

Judge Dan Rozak handed down the sentence to Christopher Vaughn Tuesday morning at the Will County Courthouse for the deaths of Kimberly Vaughn, 34; Abigayle Vaughn, 12; Cassandra Vaughn, 11; and Blake Vaughn, 8.

Before the sentencing portion began, Rozak responded to a motion for a new trial filed by Vaughn's attorney, George Lenard. The motion claimed 51 grounds, among them a contention Vaughn's trial was negatively impacted by the concurrent Drew Peterson case, an alleged indoctrinated juror, improper statements in the closing rebuttal by an assistant state's attorney and quick jury deliberations.
