For eight years, crowds gathered on a hillside above Lake Bracciano where Gisella Cardia said a statuette of the Virgin wept blood and delivered monthly messages; court-commissioned genetic testing found the traces on the statue matched Cardia's own DNA, the bishop ruled constat de non supernaturalitate in March 2024 with Vatican confirmation in June, and the Cardias were ordered to stand trial for fraud — while Cardia, through her lawyer, maintains her innocence.

Indian guru Sathya Sai Baba (1926–2011) claimed to materialize objects — watches, jewelry, ash, lingams — from thin air before millions of followers, but multiple investigations documented sleight-of-hand, and footage from India's national broadcaster showed an assistant passing him a gold chain before 'materialization.'
