Jasveen Sangha will plead guilty to several federal drug charges, including one count of distribution of ketamine resulting in death or serious bodily injury.

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.

The so-called 'Ketamine Queen' accused of illegally selling the drugs that killed 'Friends' star Matthew Perry has agreed to plead guilty, according to federal prosecutors.
