Efforts to find a 51-year-old Sun Valley woman, whose vehicle was found near Markleeville, have been suspended.
Searchers spent five days trying to find Leslie Lee Gray, using helicopters, dogs, kayaks and quadrunners.
"We really have no viable clues," said Alpine County Sgt. Ron Michitarian. "It's been five days straight and the searchers have started walking back over their own tracks."
Michitarian said Gray's disappearance is still being actively investigated with the help of the Washoe County Sheriff's Office.
"If something else changes, we'll get the word out, but for now we've got nothing," he said. "We may do an area search a week or so down the road and recheck some areas with dogs, but we feel we've done a thorough job with what we've got."
Gray's vehicle was first seen at a popular parking spot for hikers on March 31.
When it was still there on April 5, Alpine County deputies investigated further, finding food in coolers and the keys still in the vehicle.
Search and rescue teams from Alpine and surrounding counties were mobilized and searched both sides of the Carson River's east fork, in addition to floating the river.
A criminal investigation was also opened.
Friends in Sun Valley, near Reno, said they didn't know why she was in Markleeville. Gray was reportedly en route to Texas.
