The book is far from closed on Matthew Perry’s death

Over six months after the Friends star died and was laid to rest in LA’s  Forest Lawn Memorial Park, the Los Angeles Police Department and the federal Drug Enforcement Agency are still looking into what happened last October.

“There is an open investigation with the DEA,” an LAPD spokesperson told Deadline today.

After confirming the joint investigation with the DEA earlier Tuesday,, the LAPD has just issued a more formal statement:

On October 28, 2023, the Los Angeles Police Department responded to the residence of actor Matthew Perry to conduct a death investigation.  On October 29, 2023, an autopsy of Mr. Perry was performed by the Los Angeles County Department of Medical Examiner.  On December 15, 2023, the results of the autopsy indicated that Mr. Perry died from the “acute effects of ketamine.”  Based on the Medical Examiner’s findings, the Los Angeles Police Department, with the assistance of the Drug Enforcement Administration and the United States Postal Inspection Service, has continued its investigation into the circumstances of Mr. Perry’s death.

While details such as when this phase of the probe officially started and which department is taking lead have not been made public yet, a law enforcement source tells Deadline that “there have been concerns for a while about how that much ketamine was in the deceased system.”

Though  believed by many to be sober at the time of his death, multi-Emmy nominated Canadian-American actor had a long and well-documented history of battling alcohol and prescription drugs abuse. In fact, no long before his death, Perry had been speaking aloud about his struggles and a desire to help other also fighting addiction. He detailed his past and present struggles in his 2022 best selling memoir, Friends, Lovers and the Big Terrible Thing,
