Searchers have found the body of a Hurricane man and say he, too, was a victim of Monday's flash floods in southern Utah.

Ryan Daniel Mertlich is the 20th person confirmed killed in the floods, though one other person, 6-year-old Tyson Lucas Black, is missing and presumed dead. A search for Tyson's body continued Friday in Hildale, Utah, and adjoining Colorado City, Ariz.

Mertlich's body was found late Thursday about 6 miles from his abandoned vehicle, about 7 miles south of the Utah state line, according to a Mohave County, Ariz., Sheriff's Office press release.

The Washington County, Utah, Sheriff's Office has said Mertlich was last seen when he left some family's house Monday evening.

That's about the time a storm system passed over Washington County. Flash floods swept away two vehicles in Hildale, killing three women and nine of their children — not counting Tyson.

On the north side of the same mountain range in Zion National Park, flooding killed seven people exploring a slot canyon.
