Another option is to email the la Presse reporter. His address is at the end of the article. They typically like to talk about their stories. And the la Presse story is based on reviewing the court records. The indictments were issued in January so the case is in a preliminary state.
Interestingly, the la Presse article only mentions indictments for advertising sex services, inducing someone to offer sex for money, and basically knowingly profiting from crime. No charges for drugs, rapes, or coerced sex work, though presumably the prosecutors can file a superceding indictment if they have evidence, cooperating witnesses/victims, etc.
