Elizabeth Ann Beth Miller, 14, disappeared from Idaho Springs, Colorado, on the morning of August 16, 1983. She left for a routine run in white jogging shorts, a faded blue t‑shirt, and running shoes and never returned. Beth typically left a note if she planned to be away and had all her belongings and babysitting money at home, suggesting she did not intend a long absence.

Searches over the years covered the rugged terrain near Idaho Springs, including mine shafts, but turned up no trace. Witnesses reported seeing Beth speaking with a man in a small red 1975 or 1976 pickup with a white camper shell and out‑of‑state plates; the man was described as having light brown, collar‑length hair. No definitive suspects were publicly named or charged. Beth was legally declared deceased in 1994, and the Idaho Springs Police Department and Colorado Bureau of Investigation continue to list the case as active.

If anyone in Idaho Springs or the surrounding area remembers Beth on August 16, 1983, or has information about a red pickup with a camper shell seen around that time, please come forward.
