JOLIET, Ill. — Gaps and revisions in Christopher Vaughn's initial statements to investigators as to what occurred the day his wife and children were shot in the family's SUV in Channahon were highlighted by prosecutors in court Wednesday in Joliet.

For the third consecutive day, the state continued with testimony and video from the Illinois State Police investigators taking part in interviewing Vaughn, whom they claim shot his wife, Kimberly, 34, and children Abigayle, 12; Cassandra, 11; and Blake, 8, early the morning of June 14, 2007.

Vaughn's defense claims Kimberly shot her husband twice, giving him two non-life-threatening wounds, and shot the children before turning the gun on herself.
