Rain Dove Dubilewski, the gender-nonconforming model whose texts with the Italian actress Asia Argento have emerged as evidence in a potential criminal case against Ms. Argento, said Wednesday that they — Rain Dove — turned the messages over to the Los Angeles police because they believed that Ms. Argento was not being truthful. (Rain Dove prefers nongendered pronouns.)

“I turned in materials that may contribute to an honest investigation,” the model said in a statement.

In a subsequent interview with The New York Times, Rain Dove said the text exchange began when Ms. Argento reached out to them on Aug. 18, a day before The Times published an article detailing how Ms. Argento, a leading voice in the #MeToo movement, had quietly arranged to pay $380,000 to Jimmy Bennett, a young actor who said the two had had sex in a California hotel room when she was 37 and he was 17. The age of consent in that state is 18.

“They said, ‘Someone has some dirt on me,’” Rain Dove, 28, recalled, referring to Ms. Argento. “‘I’m in really, really big trouble.’”
