Daniel Born, 50, of Tucson, left a note on the morning of April 22, 2023 saying he planned to go hiking on Mt. Lemmon. That afternoon and evening his vehicle was found parked at the summit trailhead above Ski Valley, a common access point for many trails. He never returned and no one has heard from him since.

A large search followed, with the Pima County Sheriff’s Department, Pima County Search and Rescue, U.S. Customs and Border Protection and volunteers from the Southern Arizona Rescue Association conducting weeks of methodical searches in the rugged, expansive terrain. Despite those efforts, search teams found no sign of Daniel and investigators report having very little to go on. The note described a routine hike and there was no indication he had other plans; he was familiar with the area.

If anyone was on Mt. Lemmon around April 22, 2023 and remembers seeing Daniel, his car near Ski Valley, or anything unusual that day, please share what you know.
