Jasveen Sangha becomes the fifth and final defendant charged in the overdose death of the “Friends” star to strike a plea agreement with federal prosecutors, avoiding a trial that had been planned

Jasveen Sangha, who is dubbed the 'Ketamine Queen,' agreed to plead guilty to charges in connection with Matthew Perry's overdose death. Here's everything to know about the Jasveen Sangha.

Two physicians who also helped supply Perry with ketamine are awaiting sentencing. Dr. Mark Chavez, 55, of San Diego pleaded guilty to one count of conspiracy to distribute ketamine. He faces up to 10 years in federal prison at his sentencing hearing next month.
