Matthew Perry, who was an assistant, bought over $55,000 worth of ketamine in the weeks leading up to his death, according to medical records.

Kenneth Iwamasa, Matthew Perry's live-in assistant, obtained numerous vials of ketamine for the "Friends" star over several weeks, as per his plea agreement with the Department of Justice.

Iwamasa procured the drug for Perry through various sources and bought over $55,000 worth of ketamine in the months leading up to Matthew's overdose death in October 2023.

Five individuals were apprehended by authorities on Thursday in relation to the death of Perry on October 28th, among them being Iwamasa, the notorious "ketamine queen" Jasveen Sangha, doctors Salvador Plasencia and Mark Chavez, and drug broker Erik Fleming.

Iwamasa was Perry's personal assistant before his death. He is accused of conspiring with Sangha, Fleming, and Plasencia to illegally obtain ketamine and give it to Perry, as stated in court documents. Iwamasa admitted to injecting Perry with ketamine multiple times without medical training, including on the day of his death.

In September, Iwamasa introduced Perry to Dr. Salvador Plasencia, who obtained ketamine from Dr. Mark Chavez and allegedly taught the assistant how to inject Perry with the drug. Chavez, a former ketamine clinic operator, is accused of submitting a false prescription in the name of a former patient to obtain the drug.

Chavez allegedly concealed the transfer of ketamine to Plasencia by keeping possession of ketamine lozenges written on a fraudulent prescription and at least 12 vials of ketamine that he transferred to Plasencia in September and October 2023.

On Sept. 30, Plasencia administered "two shots of ketamine" to Perry at his Pacific Palisades home. He instructed Iwamasa on where to inject the drug before leaving behind a vial of ketamine with remaining liquid. Iwamasa paid Plasencia $4,500 in cash.

On October 2nd, Iwamasa requested additional drugs from Plasencia, who responded, "For 8 treatments, we can make it an even 25k" and "I will bring needles of higher gauge." Iwamasa replied that Perry was interested in purchasing "8 vials of ketamine, not ketamine treatments," and wrote, "Want to end up with 8 bottles of Dr Pepper, not just 8 sessions." Before meeting with Plasencia again, Iwamasa also secured ketamine lozenges for $2,000.

The accused defendants and Iwamasa employed code words to refer to the drugs, such as "Dr Pepper," "cans," and "bots" or "bottles," during their communications.

Iwamasa bought 9 bottles of ketamine from Plasencia between Oct. 4-8, as per the plea agreement. The two met at midnight on the Third Street Promenade in Santa Monica to exchange drugs.

On Oct. 10, Plasencia met Iwamasa in a Long Beach parking lot and administered ketamine to Perry while he was in the back seat of a car. Two days later, Perry went to a ketamine clinic at a doctor's office before returning home, where Plasencia gave him another "large dose" of the dissociative drug.

Iwamasa allegedly told Plasencia that Perry had an adverse medical reaction, which caused his blood to spike and his body to "freeze up," preventing him from moving or talking. Plasencia then reportedly instructed Iwamasa not to repeat the incident before leaving additional vials of ketamine with him.

On the day before Perry's death, Plasencia allegedly texted Iwamasa, "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 when I'm out of town this weekend, I have left supplies with a nurse of mine."

Iwamasa, who had been in the dark with Plasencia, began searching for new sources of ketamine and eventually found defendant Erik Fleming. On October 10th, Iwamasa sent a text to Fleming, asking, "Hey Erik, Alfred here butler He said I can text you directly. How much do you want per bottle and what is the nice tip you want?"

According to the plea agreement, Fleming had 10ml vials of ketamine available for $300 each, with a $1,000 brokering fee. Iwamasa discussed obtaining the drug over the next few days, and Fleming shared a screenshot from his source which said, "It’s unmarked but it’s amazing - he take one and try it and I have more if he likes."

Fleming confirmed that the message was from his dealer, Jasveen Sangha, who only deals with high-end clients and celebrities. If the product was not of high quality, she would lose her business.

On Oct. 14, Fleming delivered 25 vials to Perry's Palisades home and received $6,000. On Oct. 23, Iwamasa requested the same amount, and the following day, Fleming delivered the ketamine and received another $6,000.

On October 24th to October 27th, Iwamasa administered Perry ketamine six to eight times a day, according to authorities. On August 7th, Iwamasa pleaded guilty to one count of conspiring to distribute ketamine that resulted in death.

Sangha and Plasencia are accused of conspiring to distribute ketamine, while Sangha is also charged with maintaining a drug-involved premises, possessing methamphetamine with intent to distribute, possessing ketamine with intent to distribute, and distributing ketamine five times.

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

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.

On October 28, at his California home, Perry, who was 54 years old, tragically passed away from an apparent drowning, according to law enforcement sources that were previously confirmed to Planet Chronicle Digital.

The autopsy of the individual was completed on October 29 by the County of Los Angeles Department of Medical Examiner, with the initial cause of death listed as "deferred," awaiting toxicology results.

The autopsy report of Perry revealed that the actor died from "acute effects of ketamine," along with "coronary artery disease, buprenorphrine effects" contributing to his death.
