Matthew Perry's Death Sparks Legal Actions Against Ketamine Suppliers

Five individuals, including two doctors and Perry's assistant, face charges related to the late actor's ketamine overdose.

Kayti Edwards, Perry's ex, disputes the ketamine overdose theory, citing his fear of needles.
Prosecutors allege 'Ketamine Queen' Jasveen Sangha supplied Perry with the drug, referring to him by a character name.
Assistant Kenneth Iwamasa admitted to injecting Perry with ketamine multiple times, including on the day of his death.
Dr. Salvador Plasencia, charged in the case, has been allowed to reopen his practice under strict conditions.
Authorities suggest Sangha may be linked to other ketamine-related deaths beyond Perry's.
