JOLIET, Ill. (AP) -- A suburban Chicago man accused of killing his wife and three children has pleaded not guilty.
Christopher Vaughn entered his plea during a brief appearance in a Will County court.
He's accused of shooting his family members, whose bodies were found June 14 in an SUV parked on a frontage road near Channahon, about 40 miles southwest of Chicago.
Vaughn was arrested on June 23 at a funeral home in a St. Louis suburb, just hours before a memorial service for his family.
He's accused of killing Kimberly Vaughn, 34, and her three children, Abigayle Elizabeth, 12, Cassandra Ellen, 11, and Blake Philip, 8.
