Searchers have stopped looking for the body of a 6-year-old boy washed away in a flash flood in Hildale — at least for a few days.

Hildale Fire Chief Kevin Barlow said searchers could return to the Utah-Arizona line this weekend to search a 12-mile stretch of wash where Tyson Lucas Black's body may be buried.

"There's a break from the active search efforts to give it more time," Barlow said, "and then we'll reconsider, perhaps toward the weekend, bringing in some resources again to do another sweep."

Tyson is believed to be the 13th fatality of waters that rushed through Hildale on Sept. 14, sweeping away two vehicles.

The same storm system flooded a slot canyon in Zion National Park, killing seven people there, and a wash near Hurricane, killing one man there.

Twenty bodies have been recovered. Only Tyson's body is unaccounted for.

Dozens of people from search and rescue teams in surrounding counties, the Utah National Guard, an urban search and rescue team from Salt Lake City and cadaver dogs and their handlers have searched for Tyson.

Utah's Washington County Sheriff's Office had been coordinating the search, but on Tuesday announced it was turning control of the search to officials in Hildale and adjacent Colorado City, Ariz.

"We'll be there whenever they need our help," Washington County Chief Deputy Sheriff Shauna Jones said Tuesday.

Barlow discouraged untrained volunteers from looking for Tyson. He said banks of the wash are still eroding and breaking away and there is standing water in some locations.

Barlow described himself as "disappointed, but with great hope."
