Jasveen Sangha, known as the 'Ketamine Queen', has pleaded guilty to selling ketamine to actor Matthew Perry, which led to his overdose death. She faces up to 65 years in prison for multiple drug-related charges. Perry's family attended the court proceedings, marking their first appearance since the indictments. Sangha's plea deal comes after a year-long investigation, with other defendants also pleading guilty. Perry, who struggled with addiction, died at 54 after seeking ketamine illegally despite previously being in recovery.
