Dog owner buries human leg his pet brought home, calls police four days later (UPI) -- Authorities are on the lookout for more human remains in Washington state after finding out over the weekend about a human leg that a dog dragged home to her owner last Tuesday. Liberty brought the leg back home to her owner, 93-year-old Bill Flowers, on the Nisqually Reservation and it took him four days to call police. Flowers was apparently worried about being accused of murdering the person. I was afraid to call. I'm 93 years old. I didn't want to have to go to the pen for something I didn't do," Flowers said. Flowers buried the leg, which was dismembered about four inches from the buttocks, in his backyard. "I examined it," Flowers said. I picked it up, and looked at the toes and nothing. None of the leg or foot was damaged -- from the knee down it wasn't damaged at all. He finally alerted authorities because of the urging of his daughter. "When I got home he told me, and I said, 'Dad we have to call the police'," Cheryl Flowers said. In the hopes of finding the rest of the body, detectives put a GPS collar on Liberty. That didn't work, but search and rescue dogs found more remains -- a pelvis and rib cage -- on Sunday near the Nisqually Tribe's old fish hatchery. A pathologist will examine the remains to determine if it is a man or woman how the body was dismembered.
