Ketamine Queen, Matthew Perry's assistant, tried to conceal his overdose, according to medical records.

In the days after Matthew Perry's death, his assistant and alleged drug dealers tried to conceal the "Friends" star's ketamine overdose.

According to a plea agreement obtained by Planet Chronicle Digital, Perry's assistant Kenneth Iwamasa, along with middleman Erik Fleming and "Ketamine Queen" Jasveen Sangha, worked to destroy evidence that showed the actor was injected with ketamine multiple times on Oct. 28, provided by the trio.

Immediately after learning of Perry's death, Fleming and the "Ketamine Queen" tried to conceal their involvement in the incident, as per court documents. During a call on Oct. 28, Sangha and Fleming discussed distancing themselves from the drug deal by deleting digital evidence from their cellphones.

The court documents stated that Fleming was instructed by Sangha to erase all text messages exchanged between them and to update Signal's settings to automatically delete messages.

On Oct. 30, two days after Perry's death, Fleming and Perry's personal assistant spoke on the phone. Iwamasa admitted to "cleaning up the scene" by removing syringes and ketamine vials, as per the plea agreement.

Iwamasa asserted that he had "deleted everything," while Fleming appeared to shift responsibility onto Iwamasa in text messages to the "Ketamine Queen."

"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?""

On Oct. 28, Perry was killed by ketamine allegedly provided by Sangha and delivered to Iwamasa by Fleming.

At 8:30 a.m., Perry's assistant administered a shot of ketamine to the actor. By 12:45 p.m., Perry instructed Iwamasa to give him another injection while watching a movie. About 40 minutes later, Perry allegedly requested another injection, saying, "Shoot me up with a big one," according to 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?" — Erik Fleming

While Perry was in a Jacuzzi, the live-in assistant administered a third injection. After leaving the home to run errands, Iwamasa returned to find Perry "face down" in the Jacuzzi, deceased.

• On Oct. 10, Iwamasa encountered Dr. Plasencia in a Long Beach, Calif. parking lot and received a ketamine injection from him with Perry in the back seat. Following this encounter, Iwamasa started searching for alternative ketamine sources for Perry.
• Fleming received a text from Iwamasa regarding ketamine prices. Fleming had 10ml vials of the drug available at $300 each, and requested a $1,000 broker fee.
• Iwamasa approved the sample and requested 25 vials at $5500, with an additional $500 for logistics.
• On Oct. 14, Perry's house received 25 vials of ketamine, which were paid for with $6,000 of his money by Iwamasa.
• Fleming received a text message from Iwamasa requesting to purchase the same amount of ketamine as the previous week.
• On October 24th, Fleming handed over 25 vials of ketamine to Perry's residence at the same $6,000 price.
• Iwamasa received a text from Plasencia on Oct. 27, which read: "Hi, I know you mentioned taking a break. I have been stocking up on supplies in the meantime. I am not sure when you guys plan to resume, but in case it's this weekend and I'm out of town, I have left supplies with a nurse of mine."
• Oct. 28 – Perry died.

According to an autopsy completed on Oct. 29, the acute effects of ketamine were the cause of Perry's death. Drowning, coronary artery disease, and buprenorphine effects were also listed as contributing factors.

On Oct. 14, Fleming reportedly delivered 25 vials of ketamine, and on Oct. 24, he delivered another 25 vials. According to court documents, Iwamasa administered these vials to Perry six to eight times a day between Oct. 24 and Oct. 27.

Perry died after experiencing adverse reactions to ketamine injections administered by his untrained assistant multiple times.

In October, Iwamasa discovered Perry unconscious at least twice at the actor's residence. Iwamasa pleaded guilty on Aug. 7 to one count of conspiracy to distribute ketamine, resulting in death.

"The Ketamine Queen" is charged with six counts related to drug distribution, including one count of conspiracy to distribute ketamine and five counts of distributing ketamine. Additionally, she is accused of maintaining a drug-involved premises and possessing with intent to distribute methamphetamine and ketamine.

On Aug. 8, Fleming pleaded guilty to one count of conspiracy to distribute ketamine and one count of distribution of ketamine resulting in death. In court documents, Fleming admitted to distributing the ketamine that killed Perry and agreed to a plea deal.

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

In September 2023, Dr. Salvador Plasencia, a ketamine supplier, was introduced to Perry by his assistant. Plasencia, who obtained ketamine from Dr. Mark Chavez, allegedly taught the assistant how to inject Perry with the drug. Chavez, who previously ran a ketamine clinic, is accused of submitting a false prescription in the name of a former patient to obtain the drug.

Chavez pleaded guilty to one count of conspiracy to distribute ketamine as part of his plea agreement. He 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.
