Peter J. Cowley, a 35-year-old British tourist from Lambeth, South London, disappeared while hiking in the rugged mountains near Sitka, Alaska. He was last seen on July 10, 1992, when he set out into the backcountry and failed to return as expected.

Local authorities, including the Sitka Police Department and the Alaska State Troopers, launched a search and rescue operation in the area where he was believed to be hiking, but search teams turned up no trace of him or his belongings. The active search was eventually suspended and the case grew cold; Peter is presumed deceased, though no remains or definitive evidence have been found. The circumstances suggest a possible hiking accident, but without physical evidence that cannot be confirmed.

If anyone knew Peter, saw him in Sitka in July 1992, or has information about his route or last movements, please come forward.
