Somerton Man

Following a public appeal by police, the book from which the page had been torn was located. On the inside back cover, detectives read through indentations left from previous handwriting: a local telephone number, another unidentified number, and text that resembled a coded message. The text has not been deciphered or interpreted in a way that satisfies authorities on the case.
Since the early stages of the police investigation, the case has been considered "one of Australia's most profound mysteries". There has been intense speculation ever since regarding the identity of the victim, the cause of his death, and the events leading up to it. Public interest in the case remains significant for several reasons: the death occurred at a time of heightened international tensions following the beginning of the Cold War; the apparent involvement of a secret code; the possible use of an undetectable poison; and the inability or unwillingness of authorities to identify the dead man.
On 26 July 2022, University of Adelaide professor Derek Abbott, in association with genealogist Colleen M. Fitzpatrick, concluded the man was Carl "Charles" Webb, an electrical engineer and instrument maker born in 1905, based on genetic genealogy from DNA of the man's hair. South Australia Police and Forensic Science South Australia did not verify the result, although they were hopeful of being able to do so.
To do this, Fitzpatrick and Abbott started with a match in a DNA database (a "genetic cousin" of the Somerton Man) and then traced his family tree until they found someone who fit the profile they were looking for. Provided by Wikipedia
