The hunt for the infamous “CryptoQueen,” Ruja Ignatova, took a dark turn as an investigation by Bulgarian news outlet Bird reported that she was killed in 2018, citing documents reportedly found in the possession of a murdered Bulgarian police official.

Ignatova was head of the multimillion-dollar OneCoin scam and disappeared after allegedly fleecing investors out of as much as $5 billion in 2017. She was added to international fugitive lists, including the FBI’s ten most wanted and Europe’s most wanted list. If the Bird report is true, she achieved this notoriety last summer—up to two years after her supposed death.
