Elena Cohen, a Canadian musician who began posting on YouTube in 2006 under the name "elena xx," gained early fame with her unique and breathtaking voice. By 2011, her channel had attracted a notable following, reaching 10,000 subscribers and showcasing impressive covers and original songs. However, her promising career abruptly halted at the end of 2011. Over the following years, Elena posted infrequently and eventually removed all her videos and social media presence, effectively disappearing from the internet.

This sudden departure left her fans puzzled and concerned. A year after she removed her content, a cryptic comment on her remaining video suggested that Elena was no longer alive, which added to the mystery. An investigation into the comment revealed that the account owner, known as "e thunder," had an obsessive interest in Elena, posting extensively about her on various forums. Despite these unsettling clues, Elena's whereabouts and reasons for her disappearance remain unresolved.
