Utah has many missing persons cases and mysteries within its national forests and national parks. One of those happen to be the disappearance of a Finnish man who went missing in the Ashley National Forest in March 2025. He went to look for gold in the Uinta mountains and hasn’t been seen since. He is just a young man far from home, drawn to a wilderness he may not have fully understood. In places like this, it doesn’t take a dramatic moment for things to go wrong — just cold, isolation, and one missed turn.

Tips: If you have any information about Onni’s whereabouts or have been in contact with him, please reach out to Cpt. John Crowley at Duchesne County Sheriff’s Office by calling 435-738-1126 or emailing jcrowley@duchesne.utah.gov.
