'Trust your dog': extraordinary pets help solve crimes by finding bodies

After grueling training, a rare few civilians and their dogs are allowed to participate in criminal investigations by searching for cadavers

Rob Ward keeps baby wipes, canned soup, and bottled water in his truck. "If I need a bath or a meal, there it is," he explained in a Walker, Louisiana Waffle House. Calls can come at anytime, and his truck remains loaded, his bag packed.

Today is a rare day off from both of his jobs: a nine to five at a printing company and volunteer work looking for dead bodies with his Australian shepherd, Niko. Ward and Niko are one of approximately 500 volunteer cadaver dog-handler pairs across the country who assist law enforcement in recovering human remains.
