A second female celebrity has reportedly been linked to the death of Matthew Perry amid claims of a shared drug addiction between the two.

Matthew Perry ‘s sudden death last October shocked the world and now another celebrity might be involved in his death. The beloved Friends actor died from “acute effects of ketamine” and was found dead in his hot tub at his Los Angeles home. After his death, an investigation was started by the Los Angeles Police Department.

The investigation now includes the LAPD, the US Drug Enforcement Administration and the US Postal Inspection Service. Through the investigation, officials are hoping to find out who gave the beloved actor the lethal dose of ketamine.

A second celebrity, an anonymous woman, has been linked to his death, according to InTouch. A source told the outlet that this woman and Matthew appeared to be sober to those around them but were “walking pharmacies.”

The source claims the two had various late night talks about their lives and struggles with addictions. There’s also an alleged photo of the two at the office of a doctor who prescribes ketamine.

InTouch reports: “The source believes Matthew and the second celebrity pal may have ‘aided’ each other by referring each other to their respective doctors whenever their own drug supply ran low.”

The first celebrity to be linked to Matthew was actress Brooke Mueller, who was married to Charlie Sheen from 2008 to 2011. She was reportedly “brought in for questioning” after officials took an iPhone and laptop from her room at a sober living house.

Brooke reportedly was “completely cooperative with authorities” and shared that the two met in rehab and “formed an unexpected friendship.” Charlie’s legal council, Gregory J. Pedrick, said to InTouch: “I believe Ms. Mueller’s past choices may have put her in a position to provide some incidental, anecdotal background to the authorities investigating Mr. Perry’s death. Nothing more.”

Following Matthew’s death, court documents show that he left behind a personal wealth of more than $1.5 million (about £1.2m). The money is held in a previously established trust fund that’s valued at over $120 million (about £94.4m).

Before his death, he formed the “Alvy Singer Living Trust,” inspired by Woody Allen’s character from the film, Annie Hall. The beneficiaries include his father John Perry, mother Suzanne Morrison, half-sister Caitlin Morrison, and his former love interest, Rachel Dunn, with whom he had a brief relationship from 2003-2004.
