A flash flood in the Grand Canyon leaves a Texas chiropractor and members of his hiking group unaccounted for, according to reports from family and news outlets. Dr. John Giusti’s wife says he and members of the hiking party are among those still missing after the flood tore through the area.

The incident occurs in a region known for rapidly changing weather and sudden water surges. While details about the number of people affected and the exact location of the group are reported inconsistently across coverage, all accounts agree that authorities are working to account for people after the water event. Fox News and Yahoo News both cite the same missing-person claim from Giusti’s wife, describing him as a chiropractor from Texas and characterizing the group as hikers.

At this stage, outlets focus primarily on the identities of those reported missing and the response to locate them, rather than on a confirmed overall casualty or recovery total. Further official updates are expected as search efforts continue.
