Authorities in southern Utah say a flash flood kills five family members, including a Provo fire captain, his wife, and their three sons. The victims were reportedly hiking in a canyon area near a campground and were caught in heavy rains that led to flooding. Multiple outlets identify the father as a captain in the Provo, Utah, fire department and his wife and three sons as the other victims. Officials describe the incident as a likely flood-related death, with searches and confirmation occurring after the weekend. The Guardian also reports that the family has a daughter who was not part of the hiking party and survives. The accounts are consistent in naming the victims, describing where they were when the flood occurred, and attributing the deaths to a flash flood during storms in the region. Further details about the exact location, timing, and weather conditions are not included in the provided summaries.
