UPDATE:
GRAND CANYON NATIONAL PARK, Ariz. -- Authorities are searching for a 14-year-old Chattanooga boy and a 62-year-old woman missing in Grand Canyon National Park after they were swept down a creek while crossing it in a remote part of the park.
Chief Ranger Matt Vandzura of the National Park Service says two fellow hikers alerted authorities by setting off an emergency GPS locator beacon in the backcountry area below the canyon's North Rim.
One of the missing hikers has been identified as McCallie eighth-grader Jackson Standefer.
He says the two lost their footing and were swept away Saturday in Tapeats Creek, a tributary of the Colorado River.
An investigation is underway but authorities have not concluded how the two were swept away.
A helicopter and a drone on Monday were assisting searchers on the ground.
In a statement to WRCB on Monday, Standefer's family said:
"Last night at 9 pm local time and 12 EST the search and rescue met with the families. There is nothing new to report. Search and rescue logged 300 man hours yesterday in the search. Rescuers were in the canyon searching all night. They are sending in drones at 7am to scour the wall of the slot canyon they think they could be in. The out look is not promising but there is still a glimmer of hope. We will hold on to this hope until there is reason not to. Please keep praying."
