Matthew Perry’s death under investigation for ketamine source

Los Angeles police are investigating the source of the ketamine drug that killed actor Matthew Perry last year.

L.A. police said Tuesday that they are still investigating Perry’s death with assistance from the Drug Enforcement Administration and the U.S. Postal Service. The investigation, which has been ongoing since an autopsy was released last year, is focused on “the source of the ketamine” linked to Perry’s death, Capt. Scot Williams said in an email.
