Officer Kate Lines, Pg 39 (Discovery pg 84) - I entered the home with Jayne and her K9 (a cadaver dog). As we moved through the home, Jayne explained what type of scent the dog alerts to. Jayne mentioned several times that the dog alerted to areas where there may have been some sort of trauma or struggle such as an argument, explaining that scent from people, pools and collects in areas. Jayne’s dog was later taken to Chris’s work truck, which was parked just east of his home. Jayne stated that the dog detected but gave no hard command, however, the dog did not enter the vehicle, and the doors were closed.
