Body of last missing hiker found after Grand Canyon flooding

Human remains found in the Grand Canyon this week were those of the last remaining person missing after deadly flash flooding in late August, officials and the victim's wife said Thursday.

The discovery of Timothy Allen Smith brought the death toll to three from flooding that devastated the Phantom Ranch area at the canyon bottom and damaged the water pipeline serving the South Rim.

Smith, 53, was a pilot from western Wyoming's Star Valley. His remains were found Monday near Crystal Rapids on the Colorado River that runs through the canyon.

The remains of Smith's two backcountry companions, Brent Rosenkranz, 42, and John Giusti, 46, both of Granbury, Texas, were found earlier.

Smith grew up in Granbury and lived with his wife in Star Valley Ranch, about 40 miles southwest of Jackson.

He, Rosenkranz and Giusti were on a multiday hiking, fishing and camping trip when flooding swept through the Grand Canyon. Their plan was to spend two nights exploring trails near the bottom of the canyon and go fishing before moving on to Havasupai Gardens, which the park says is a "frequent stop for hikers and mule trains traveling up and down the Bright Angel Trail," before finishing their hike, according to a statement from their families.

During the two-day deluge, searchers used night vision and other equipment to find people in need of rescue. They relied on the Grand Canyon National Park's permit system and checked vehicle license plates to track those still missing. More than 80 people were rescued.

Soon, only Smith was missing. In a Facebook video at the time, his wife, Carrie, and their children thanked people for their support and prayers.

On Tuesday morning, Carrie Smith posted on Facebook that the family was aware a body had been found a day earlier and asked others to pray with them.

Smith confirmed in a Facebook post on Thursday that the remains had been identified as her husband's.

"My family has done a lot of waiting over the last three weeks … waiting and hoping Tim (Daddy) would come home, waiting and wondering if the remains found were Tim (Daddy)," she wrote. "We no longer have to wait, Tim was found two days ago by the Rangers at Grand Canyon National Park. Not in the way we had hoped, but we know that he was doing something he loved with John and Brent."

She added, "We know that these three men loved the Lord and were a shining light for Him. The impact their lives had on others is still being shown to our families daily."

The National Park Service said Smith's body was located along the Colorado River on Monday and his identity was confirmed by the Coconino County Medical Examiner in Arizona.

"The National Park Service extends its deepest condolences to the families and friends of Tim Smith, John Giusti and Brent Rosenkranz," the agency said in a statement to CBS News. "We are grateful to the search teams and partner agencies whose personnel worked tirelessly in difficult conditions over the past several weeks on search and recovery efforts."
