Text messages presented during the investigation revealed a concerning rapport between Plasencia and Perry. The doctor allegedly referred to Perry with derogatory terms and inquired about the actor's willingness to pay for illicit drugs. According to the plea documents, Plasencia provided ketamine injections at Perry's residence and in public areas, specifically in a parking lot at the Long Beach Aquarium. He also taught Perry’s assistant—who is one of the other defendants—how to administer the drug. Prosecutors have described a broader underground network involving five individuals who allegedly facilitated Perry's access to the drug, showcasing how prescription medication was mismanaged.

The plea agreement indicates that between September 30 and October 12, 2023, Plasencia sold Perry and his assistant multiple vials of ketamine, far exceeding the prescribed legal limit intended for depression treatment. Efforts to contact Plasencia's legal representatives for further comments were unsuccessful. The shocking circumstances surrounding Perry’s death have left fans and the entertainment industry reeling, intensifying discussions about addiction and the responsibilities of medical professionals.
