david wright has the story. reporter: the most grueling sled dog race in the world. a thousand miles through the alaskan tundra was too much for 3-year-old sirabi, her musher dropped her midway through because of a sore shoulder. even though she wanted to stay in the race i made the decision to leave her at the checkpoint. obviously she wasn t done running. rape she managed to escape in anchorage and went missing for a month volunteers passed out flyers and hung posters in hopes of finding her. turns out she mushed herself to glacier view 100 miles away and last week turned up again this time poking around a church in palmer, 40 miles from anchorage. two ladies in a car looking for her stopped and mentioned she had seen her walk through our backyard. the reverend tim kerrick mounted a camera and put out food. i checked the sd card and there was over 250 pictures.
