Nickerson and her husband, both visitors from Gilbert, Ariz., were swept into Havasu Creek, about 800 metres from where the creek feeds into the Colorado River. Nickerson’s husband was rescued by a group of rafters, according to KPNX of Phoenix , but Nickerson herself was nowhere to be found.

Rangers at the Grand Canyon National Park searched for Nickerson for days with no sign of the missing 33-year-old. The National Park Service appealed to the public for help locating Nickerson, who they said was not wearing a life jacket when she was swept away.
