Onni Raassina, a 28-year-old Finnish man, was last seen on March 5, 2025, after arriving at Salt Lake City International Airport in Utah. He had traveled from Finland with plans to visit the Moon Lake area in Duchesne County. However, it remains unclear if he ever reached his intended destination. Onni was reportedly driven to the Moon Lake Lodge by a yellow cab, as he was interested in exploring the Uinta Mountains, inspired by stories of buried treasure in the area.
His family reported him missing on March 17, 2025, after not hearing from him for nearly two weeks.
Authorities have been actively investigating Onni's disappearance. His phone last pinged in the Moon Lake area, approximately 150 miles east of Salt Lake City, but no further clues have been uncovered. The Duchesne County Sheriff's Office has noted that Onni did not appear to have the appropriate equipment for the harsh winter conditions in the Uintas. The campground in the area remains closed during this season, adding to the challenges of the search. Onni's family has traveled to Utah to assist in the search efforts.
Onni is described as a white male with short blonde hair and blue eyes, standing 5'9" tall and weighing 165 pounds. He was last seen wearing a gray hoodie, black jeans, and carrying a black backpack. Despite extensive search efforts, his whereabouts and the circumstances surrounding his disappearance remain unknown. The case is classified as endangered missing, and authorities continue to seek public assistance in locating him. Anyone with information is urged to contact the Duchesne County Sheriff's Office.Last Seen: Mar 5, 2025
