Matthew Perry's Assistant, Ketamine Queen Attempted to Cover Up Actor's Overdose

Matthew Perry's assistant and drug dealers attempted to cover up the "Friends" star's ketamine overdose in the days after his death.

Perry's assistant, Kenneth Iwamasa, along with middleman Erik Fleming and Jasveen Sangha, aka the "Ketamine Queen," worked to get rid of evidence showing the actor was injected multiple times with ketamine provided by the trio on October 28, according to a plea agreement.

Fleming and the "Ketamine Queen" first attempted to cover up their involvement in the late actor's death immediately after learning the news, according to the court documents. 

During a call on October 28, Sangha and Fleming discussed distancing themselves from the drug deal by "deleting digital evidence" from their phones.

Sangha instructed Fleming to delete all text messages shared between the two and updated the encrypted messaging appSignal settings to automatically delete messages, the court docs read.

They spoke on the phone on October 30, two days after Perry's death. Iwamasa revealed he had "cleaned up the scene" by getting rid of the syringes and ketamine vials and also claimed he "deleted everything,". Fleming seemingly placed blame on Iwamasa in text messages to the "Ketamine Queen."

"Please call... Got more info and want to bounce ideas off you," the middleman wrote in a text message included in the plea agreement. "I'm 90% sure everyone is protected. I never dealt with [Victim M.P.]. Only his Assistant. So the Assistant was the enabler. Also, are they doing a 3-month tox screening ... Does K stay in your system or is it immediately flushed out?".

The ketamine allegedly provided by Sangha and delivered to Iwamasa by Fleming killed Perry on October 28. That morning, Perry's assistant administered a shot of ketamine to the actor around 8:30. By 12:45 p.m., Perry had instructed Iwamasa to give him another injection while the "Friends" star watched a movie. 

Roughly 40 minutes later, the star requested another injection, allegedly telling Iwamasa, "Shoot me up with a big one," according to the plea agreement.

The live-in assistant administered a third injection to Perry while the 54-year-old was near or in a Jacuzzi. Iwamasa then left the home to run errands for Perry. When he returned, the assistant found Perry "face down" in the Jacuzzi, deceased.

• October 10 – Iwamasa met Dr. Plasencia in a parking lot in Long Beach, Calif., with Perry sitting in the back seat for Plasencia to administer one shot of ketamine. On the same day, Iwamasa began looking for alternative sources of ketamine for Perry.
• October 10 – Iwamasa texted Fleming about ketamine prices. Fleming had 10ml vials of the drug for $300 each and requested a $1,000 broker fee.
• October 13 – Fleming delivered a sample, which Iwamasa said "seems good" and requested "25 vials $5500 @220 +500 for logistics."
• October 14 – Fleming delivered 25 vials of ketamine to Perry’s house, which Iwamasa paid for with $6,000 of Perry’s money.
• October 23 – Iwamasa texted Fleming to purchase more ketamine in the same amount as the week before
• October 24 – Fleming delivered 25 vials of ketamine to Perry’s house, the same $6,000 price.
• October 27 – Plasencia texted Iwamasa, "Hi I know you mentioned taking a break. I have been stocking up on the meanwhile. I am not sure when you guys plan to resume but in case its when im out of town this weekend I have left supplies with a nurse of mine."
• October 28 – Perry died.

Perry's death was caused by "acute effects of ketamine," according to his autopsy completed on October 29. Drowning, coronary artery disease, and buprenorphine effects were listed as contributing factors.

Fleming allegedly delivered 25 vials of ketamine on October 14 and an additional 25 vials on October 24. Iwamasa used the vials to inject Perry six to eight times a day between October 24 and October 27, the court documents claimed.

Perry had an adverse reaction to the ketamine injections, given by his assistant who had no medical training, multiple times before he died. 

Iwamasa found Perry unconscious at least two times at his home throughout October, the assistant's plea agreement read. Iwamasa pleaded guilty on August 7 to one count of conspiracy to distribute ketamine, causing death.

Sangha was charged with one count of conspiracy to distribute ketamine, one count of maintaining drug-involved premises, one count of possession with intent to distribute methamphetamine, one count of possession with intent to distribute ketamine, and five counts of distribution of ketamine.

Fleming pleaded guilty on August 8 to one count of conspiracy to distribute ketamine and one count of distribution of ketamine resulting in death. He admitted in court documents to distributing the ketamine that killed Perry. Fleming also agreed to a plea deal.

Two doctors have also been charged in connection to Perry's death.

Dr. Salvador Plasencia, a ketamine source, was introduced to Perry by his assistant in September 2023. Plasencia obtained ketamine from Dr. Mark Chavez and allegedly taught the assistant how to inject Perry with the drug. 

Chavez previously ran a ketamine clinic and allegedly submitted a bogus prescription in the name of a former patient to secure the drug. He agreed to plead guilty to one count of conspiracy to distribute ketamine as part of the plea agreement. 

The San Diego-based doctor admitted to selling ketamine to Plasencia, including ketamine that he had diverted from his former ketamine clinic. Plasencia pleaded not guilty to one count of conspiracy to distribute ketamine.
