On Monday afternoon, a 35-year-old visitor from Germany was hiking on the Hugh Norris Trail with a partner, also from Germany, when she collapsed. Her partner attempted to revive her with water, but was unsuccessful. He then ran down the trail to his vehicle and drove to the visitor center to report the incident. A ranger and personnel from Picture Rocks Fire Department responded. When they got to the woman’s location, they found that she had expired. Investigation revealed that the couple had headed out for Wesson Peak at 7 a.m. and reached the summit just before 11 a.m. While on the return trip, she told her partner that she was not feeling well. Shortly thereafter, she collapsed and became unconscious. Neither was carrying a cell phone and help was not readily available. The temperature high for Tucson that day was 105 degrees. The Pima County Sheriff’s Department is leading the investigation.
