In 1970, an unidentified woman was found dead in Norway's Isdalen valley. 56 long years later, her identity and the full story behind her death remain unresolved to date

The Isdal Woman mystery began in November 1970, when a burned body was discovered in Norway’s remote Isdalen Valley near Bergen. Investigators found unusual clues, including belongings with identifying labels removed, two suitcases containing wigs and clothes, and notes that appeared to record hotel stays under different names. Her identity was never established, while the circumstances surrounding her death led to theories ranging from espionage to other unexplained possibilities. Although the case was closed in 1971, renewed investigations decades later examined her background, movements and physical evidence. Yet 56 years later, her identity and the full story remain unresolved.
