Border Patrol to join hunt for hiker missing in Grand Canyon flooding

A specialized Border Patrol team is assisting in the search for a hiker missing in the Grand Canyon following deadly flash floods. Families confirmed that John Guisti, 46, and Brent Rosenkranz, 42, were killed in the flooding, which also forced dozens of evacuations over the weekend. These dangerous events are common across the Southwest during the monsoon season, where even minimal rainfall can quickly escalate into life-threatening floods, supercharging the risks for hikers in the region.
