Arizona Grandfather Faces Amputation After 120-Degree Heat Collapse

A 72-year-old Arizona grandfather, Grant Siler, collapsed on a Bullhead City sidewalk on Aug. 3 after walking in 120-degree heat, suffering extensive second- and third-degree burns and heat-related illness that left him on the ground for about an hour. He was rushed to a Las Vegas burn ICU, where doctors found heat stroke and organ shock, with his core temperature around 105 degrees and limited mobility as he endured severe pain. Surgeons later determined that the tissue in his right leg was so severely damaged that healing would be unlikely, and he is scheduled for an above-the-knee amputation on Aug. 31 to improve healing and pain control, after multiple debridements. His family has started a GoFundMe to cover medical expenses, home modifications, and prosthetics as his wife travels long distances to support him during a lengthy and challenging recovery. The case highlights how extreme heat can rapidly turn a simple walk into life-threatening injuries, underscoring the ongoing health risks of heat waves in the region.
