Another Celebrity Linked to Matthew Perry's Death after Brooke Mueller Is Tied to Case

A second female celebrity has been linked to Matthew Perry's death investigation a bombshell report about their shared addiction.

An investigation into Perry's fatal ketamine overdose has uncovered involvement by another friend, InTouch reports.

The as-yet-unnamed woman was allegedly claiming to be sober, but was a 'walking pharmacy', according to a source.

Photo evidence has emerged of the woman with Perry at the office of a doctor who was prescribing him ketamine. The two would refer each other to their respective doctors to obtain the drug and would often confide in each other about their addiction battles, the source claimed. 

"'If the feds had either one of their phones — especially [the second celeb’s], because she doesn’t erase her text messages — they would probably find conversations about the drug and "How can I get extra?" Like, it will not look good for the celebrity," the source noted.

The anonymous celebrity is the second to be linked to Perry's death after Charlie Sheen's ex-wife Brooke Mueller was named. 

The criminal probe has been underway since May and includes investigators with the Los Angeles Police Department, the Drug Enforcement Administration, and the U.S. Postal Service.

Detectives are tracing the actor’s procurement of the illegal drug, which has been used recreationally for decades but has recently been discovered as useful in the treatment of depression.

Perry’s body was found by an assistant after he’d drowned in his swimming pool’s hot tub at his Pacific Palisades home on October 28 after the lethal dose of ketamine caused him to have cardiovascular overstimulation and respiratory depression, according to the Los Angeles County Medical Examiner’s office.

The amount of ketamine found in his blood was about the same as what would be used during general anesthesia, the medical examiner said.

The office lists the acute effects of the drug as the main cause of his death and added drowning, coronary artery disease and the effects of buprenorphine, a drug used to treat opioid use, as contributing factors.

Although friends of Perry confirmed the late actor was undergoing ketamine therapy, his most recent session had been a week and a half prior to his death, according to the Medical Examiner’s report. This does not explain the high levels of the drug in his system at the time of his death, as ketamine metabolizes in a few hours. No other drugs were found in Perry’s system, and there was no paraphernalia discovered in his home, officials said.

According to the medical examiner’s report, a psychiatrist and an anesthesiologist who also served as Perry’s primary care physician were the only medical professionals known to be treating Perry in October.
