Authorities Launch Investigation into Who Supplied Ketamine to Matthew Perry Before His Death

An investigation was launched to determine the origin of the ketamine that played a role in the death of Friends star Matthew Perry, according to reports.

In a development nearly seven months after Perry was found dead in his hot tub, authorities are reportedly focused on uncovering who provided the deadly drug and the circumstances surrounding the transaction, RadarOnline.com reported.

According to law enforcement sources who spoke with TMZ, the current inquiry has been ongoing for several months, with both local police and the DEA involved in the investigation.

The exact progress of the probe is still unclear.

According to reports, "key" individuals in Hollywood have been interviewed as part of the investigation — although their identities were not disclosed.

While the specific sources of the drug remain unknown, individuals with a history of drug use or abuse have reportedly been approached for possible information.

According to TMZ, no arrests have been made in connection with the case.

As RadarOnline.com previously reported, Perry was found unresponsive in the hot tub of his Pacific Palisades residence in October 2023.

Emergency responders arrived on the scene following a cardiac arrest call but were unable to revive the actor, who was pronounced dead at the scene. He was 54.

Initially suspected to be a drowning accident, the toxicology report revealed that Perry had succumbed to the acute effects of ketamine.

Despite undergoing ketamine infusion therapy for depression and anxiety in the days leading up to his death, investigators determined that the ketamine found in his system at the time of death was not from the prescribed treatment.

Perry’s Friends co-stars came together shortly after the actor’s devastating death in October to share a joint statement regarding his sudden passing.

"We are heartbroken by the tragic loss of our beloved son and brother. Matthew brought so much joy to the world, both as an actor and a friend. You all meant so much to him and we appreciate the tremendous outpouring of love," Jennifer Aniston, David Schwimmer, Courteney Cox, Matt LeBlanc, and Lisa Kudrow said in the joint statement following the news of Perry’s death.

"In time we will say more, as and when we are able," the group continued. "For now, our thoughts and our love are with Matty’s family, his friends, and everyone who loved him around the world."
