Results from the Regina crime lab cause police to change the focus of the investigation from sudden death to homicide and schedule a search warrant for November 4, the day Tracy was to have had her surgery. Robert Latimer confesses to killing Tracy. He demonstrates for police how he carried her to his pickup while his wife and other children were at church, piped exhaust fumes into the cab and waited until she was dead. He said he then carried his dead daughter inside the house, and put her in her bed in the room she shared with her brother. Then he waited until the rest of the family came home.
