The Los Angeles Police Department, alongside federal agencies including the DEA and the US Postal Inspection Service, is investigating the source of the ketamine that led to the death of actor Matthew Perry. Perry, known for his role in 'Friends,' was found dead at his Pacific Palisades home on October 28, 2023, with acute effects of ketamine and drowning cited as the cause of death. Despite undergoing ketamine infusion therapy for depression and anxiety, the ketamine in his system at the time of death was not from his prescribed treatment. Law enforcement sources suggest that 'multiple people' could face charges, pending a decision by the US Attorney's Office. The investigation is nearing its conclusion, focusing on who supplied the actor with the fatal dose. Perry's death has raised questions about the legality of the ketamine he used, as well as the broader implications for those involved in its distribution.
