The woman who accused Ronaldo of assaulting her, Kathryn Mayorga, went to the police shortly after the incident but declined to tell investigators either the identity of her attacker or the site of the assault. The district attorney said Monday that her reluctance had made it difficult for the Las Vegas police to “conduct any meaningful investigation” at the time, and the case was closed. The next year, the district attorney’s statement noted, Mayorga reached a civil settlement with Ronaldo.

The case first attracted limited public attention in 2017, when the German magazine Der Spiegel reported on the sexual assault allegation and the $375,000 settlement paid to Mayorga. Last year, Der Spiegel obtained a number of documents from the whistleblower platform Football Leaks that it said supported Mayorga’s claims. They included the signed settlement agreement between Mayorga and Ronaldo, a sexual-assault medical examination and correspondence between lawyers representing Ronaldo.

Included in the correspondence were two questionnaires with answers submitted by Ronaldo. According to Der Spiegel, in the first version of the questionnaire Ronaldo responded that Mayorga had “said no and stop several times” and that “she said that she didn’t want to, but made herself available.” Those answers are not in the second version.

In an Instagram video that was posted when the accusation resurfaced last year, Ronaldo labeled any claim of sexual assault “fake news.” His representatives have maintained that any contact between Ronaldo and Mayorga was consensual.

Der Spiegel also published an interview in which Mayorga put her name behind the accusation. In it, her lawyer said she had sustained psychological trauma from the attack and therefore was not legally able to agree to the civil settlement and associated nondisclosure agreement she signed in 2010.
