After a DJ working at the wedding announced that she was missing, guests immediately started looking for her, and after an hour of searching, a police report was filed.

[6] Nordahl Lelandais, an ex-soldier who attended the wedding, was taken into custody in September 2017 after traces of De Araujo's DNA were found in his Audi A3 car.

[7][8] CCTV footage showed Lelandais leaving the wedding venue with a "small, frail figure in a white dress" in the passenger seat of his car shortly before De Araujo was reported missing.

[11] On 17 February 2022, his 39th birthday, Lelandais was sentenced to life imprisonment with a minimum term of 22 years for the kidnapping and murder of De Araujo.

Other cases that may be linked to Lelandais include those of Jean-Christophe Morin and Ahmed Hamadou, who vanished from a festival in Fort de Tamié in 2011 and 2012 respectively.
