Jennifer Aniston and Courteney Cox are doing everything they can to help the investigation into Matthew Perry's death, according to a source.
Matthew was found dead at the age of 54 at his Los Angeles mansion last October. An autopsy determined his death was an accident from the acute effects of ketamine and the Los Angeles Police Department has confirmed to The Mirror they are investigating who supplied the actor with the drugs.
They're also looking into what circumstances Matthew was given the ketamine that killed him. A source has now said Matthew's Friends co-stars are "still in shock" over his death and want to help the investigation.
Jennifer and Courteney are said to have been "racking their brains" trying to recall people they might have seen with Matthew. However, the source told The Express : "It's a near-impossible task to try to figure out who might have been his private dealer or dealers."
They added: "Like the rest of the cast, Jen and Courteney have said they’ll do anything they can to help the task force find who was supplying him with such dangerous quantities of a potentially lethal drug." The source also said Matthew's Friends co-stars are worried the investigation could be like "looking for a needle in a haystack".
TMZ has reported the Drug Enforcement Administration is also involved in the investigation, as well as the USPS' federal investigatory authorities. Inspectors are reportedly offering their expertise, including package tracking and other mail-related investigation techniques.
Key Hollywood figures have been interviewed as part of the investigation, the Los Angeles Police Department confirmed. According to TMZ, those who have been spoken to "are not necessarily the actual source of ketamine", but are believed to have information which could lead to the source of the ketamine. No arrests have been made as a result of the investigation so far.
The LA County Medical Examiner's Office revealed in December that Matthew's death was drug related. The coroner's investigation into Matthew's cause of death revealed he had enough ketamine in his system to knock him unconscious for an operation.
The Medical Examiner's report also revealed that Perry had been prescribed ketamine as part of an infusion therapy treatment for depression and anxiety, and was taking it every other day. However, four months before his death, a new doctor tried to wean him off the drug.
The last time he was prescribed a dose of the drug was reportedly a week and a half before his death. The coroner noted that the ketamine in Matthew's system "could not be from that infusion therapy, since ketamine's half-life is three to four hours, or less."
