A woman who has come to be known as the Ketamine Queen pleaded guilty on Wednesday to selling Matthew Perry the drug that killed him. Jasveen Sangha changed her previous not guilty plea at a federal court in Los Angeles and became the fifth and final defendant charged in the overdose death of the Friends star to plead guilty after a deal with prosecutors. She agreed in a signed statement to plead to five federal charges, including providing the ketamine that led to Perry's death. Her trial had been planned to start later this month. In a brief statement when the deal was announced on 18 August, Sangha's lawyer Mark Geragos said only: She's taking responsibility for her actions.
