Shannon Joy Schell, 34, left a trailhead in Saguaro National Park on October 12, 1994, for a solo attempt at the Tanque Verde Ridge trail to Manning Camp, a strenuous 32-mile round trip over very rough terrain. She parked her Camaro at the trailhead and secured her wallet, money, and jewelry in the trunk, then set off carrying snacks, a couple of water bottles, extra clothing, cigarettes, lipstick, and cough drops. Shannon was living with her parents at the time, working at Jason’s Deli on Broadway Boulevard, and was recovering from the flu and bronchitis when she disappeared.

More than 120 searchers used tracking dogs, helicopters, and infrared sensors, logging over 2,000 search hours. Searchers found a fire ring, footprints, and some items that may have belonged to her about six miles up the trail, but no sign of Shannon herself. Her car stayed at the trailhead. Investigators’ prevailing theory is that she became lost or injured and succumbed to environmental exposure, though family members have considered both accident and foul play. Her body has never been recovered and the case remains unsolved.

Did anyone hike the Tanque Verde Ridge trail on or around October 12, 1994, who remembers seeing Shannon or anything unusual that day?
