On Thursday, an arrest was made in Southern California in connection with the overdose death of actor Matthew Perry, according to law enforcement sources.

Perry, 54, was discovered face down in the heated end of a pool at his Pacific Palisades home on October 28, 2023. The Los Angeles County Medical Examiner’s Office determined that his death was caused by the acute effects of ketamine, an anesthetic with psychedelic properties.

In May, Los Angeles police announced they were collaborating with federal authorities to trace the source of the ketamine Perry had used. Ketamine, known for its recreational use as a party drug, has recently gained attention as a potential treatment for depression. Many clinics now offer it as an infusion or injection for various mental health conditions.

Perry had been receiving ketamine infusion therapy for depression and anxiety, but his last session was over a week before his death. The medical examiner concluded that the ketamine in Perry’s system could not have come from this therapy, given the drug’s short duration in the body.

The ketamine levels found were high, comparable to those used for general anesthesia during surgery. The coroner ruled Perry’s death an accident, noting that drowning, coronary artery disease, and the effects of buprenorphine (used for opioid use disorder) were contributing factors.

Perry, widely recognized for his role as Chandler Bing on “Friends,” had been candid about his ongoing battles with opioid addiction and alcoholism, detailed in his 2022 memoir, “Friends, Lovers and the Big Terrible Thing.” According to the medical examiner’s report, he had been sober for 19 months at the time of his death.

It is common for law enforcement to investigate and sometimes press charges against those who provided drugs leading to high-profile deaths. For instance, after Michael Jackson’s death in 2009, his personal physician, Dr. Conrad Murray, was convicted of involuntary manslaughter for administering a fatal dose of drugs. More recently, in 2021, federal prosecutors in New York charged four individuals who supplied actor Michael K. Williams with the fentanyl-laced heroin that led to his death.
