Doctor Who Supplied Ketamine to Matthew Perry Will Plead Guilty — Full Scoop on the Drugs, Dealers & Drama

1. The Tragic Fallout That Never Ends

Matthew Perry’s death in October 2023 rocked Hollywood because it felt so preventable. The Friends star drowned in his hot tub—not after a crash, an accident, or a vanity project—but from an acute ketamine overdose, compounded by multiple substances. Since then, the LAPD and U.S. Attorney’s Office have launched an exhaustive investigation revealing a sprawling network of enablers—from doctors to dealers to insiders—each playing a role in Perry’s final days.

The latest twist? Dr. Salvador Plasencia, the last licensed professional under indictment, has agreed to plead guilty to distributing ketamine to Perry in the month before his death. He faces up to 40 years behind bars. Let’s unpack every player, every scandalous text, and every reaction—because this isn’t just legal…it’s personal.

2. The Cast of Culprits: Who Supplied What to Perry

Name	Role	Status	Charges / Notes
Dr. Salvador Plasencia	Doctor	Pleading guilty	Distributed 20 vials, injected in car, taught assistant; faces up to 40 yrs
Dr. Mark Chavez	Doctor	Pleaded guilty	Supplied ketamine lozenges via fraudulent script; faces up to 10 yrs
Kenneth Iwamasa	Assistant	Pleaded guilty	Injected Perry with ketamine, including fatal day; up to 15 yrs
Erik Fleming	Acquaintance / Dealer	Pleaded guilty	Sourced street ketamine; faces up to 25 yrs
Jasveen Sangha (“Ket Queen”)	Major Distributor	Not guilty	Supplied vials including fatal dose; trial August 2025

A. Dr. Salvador Plasencia

Nicknamed “Dr. P,” Plasencia was Perry’s primary source for ketamine vials. Court documents show he referred to the actor as “this moron” and even injected him from a parked car. He also taught Perry’s assistant how to administer doses and falsified medical records to cover his tracks.

B. Dr. Mark Chavez

A San Diego-based physician, Chavez sent Perry ketamine lozenges using fraudulent prescriptions. He stole supplies from his former ketamine clinic and is now cooperating with the prosecution.

C. Kenneth Iwamasa

Perry’s personal assistant, Iwamasa was the one who physically injected him—21 doses in the final week, including three on the day of his death. His cooperation is expected to be key in other trials.

D. Erik Fleming

Known as a street dealer, Fleming transported ketamine from Sangha to Iwamasa and deleted damning text messages afterward. He’s pleaded guilty to conspiracy to distribute drugs resulting in death.

E. Jasveen Sangha (“Ket Queen”)

Sangha supplied Fleming and Iwamasa with roughly 50 vials, despite reportedly knowing ketamine had already caused a fatality in a different case. She is the only defendant to plead not guilty, and her trial is set for August 2025.

3. The Unfolding Timeline

• Sept–Oct 2023: Plasencia starts supplying Perry with 20 vials via Iwamasa.

• Oct 12: Plasencia administers an excessive dose; Perry reacts poorly.

• Oct 24: Fleming delivers new vials to Iwamasa from Sangha.

• Oct 28: On the day of Perry’s death, Iwamasa gives three injections—then finds him unconscious.

• Post-death: Dealers delete incriminating messages in a panic.

4. Celebrity Friends Were Concerned

Perry’s friends weren’t blind. Reports suggest close confidants suspected he was using again in his final months.

Jennifer Aniston reportedly checked in with Perry frequently after noticing weight changes and erratic messaging. Courteney Cox, during an interview, noted he had become “distant,” and insiders say Lisa Kudrow even offered to stage a quiet intervention.

David Schwimmer and Matt LeBlanc were also reportedly in touch with him just weeks before his death. While no one publicly accused him of relapse, sources close to the actor said the “worry was always there.”

5. A High-Stakes Legal Reckoning

With Plasencia pleading guilty, he becomes the fourth co-conspirator to fold. Sentencing dates for the other three are still pending, while all eyes turn to Sangha’s upcoming trial.

Expected sentences if maximum penalties are applied:

• Chavez: 10 years

• Iwamasa: 15 years

• Fleming: 25 years

• Plasencia: 40 years

• Sangha: Life in prison (if convicted)

6. Addiction, Ethics & Accountability

Perry was no stranger to addiction. He was open about his 15 rehab stays, multiple surgeries, and $9 million spent trying to get clean. He believed ketamine might offer an alternative treatment—but ended up as another casualty of lax medical ethics and shady drug networks.

The case underscores a larger issue: celebrity access to potent drugs through legal and illegal channels. For many, Matthew Perry’s story is not just tragic—it’s systemic.

7. Final Take: Justice May Be Coming, But It’s Too Late

Each guilty plea brings some form of closure—but also opens fresh wounds. Perry’s death now seems less like an accident and more like the final chapter in a slow-motion betrayal.

These weren’t strangers. These were trusted professionals, confidants, and insiders. And one by one, they fed him exactly what would kill him.

The Key Players: Who are the Doctors Involved?

The federal investigation into Matthew Perry’s death uncovered a “broad underground criminal network.” Central to this network were two licensed physicians who allegedly prioritized profit over patient safety.

Dr. Mark Chavez

Dr. Mark Chavez, a 54-year-old physician from San Diego, operated a ketamine clinic. According to court documents, Chavez admitted to diverting ketamine from his own clinic and using a fraudulent prescription in a different patient’s name to obtain additional supplies of the drug.

• The Plea: Chavez has formally pleaded guilty to one count of conspiracy to distribute ketamine.

• The Connection: He allegedly sold the diverted ketamine to Dr. Salvador Plasencia, knowing it would be distributed to Perry outside of a professional medical setting.

Dr. Salvador Plasencia (known as “Dr. P”)

Dr. Salvador Plasencia, an internal medicine specialist from Santa Monica, is accused of being the primary supplier to Perry’s personal assistant in the weeks leading up to the actor’s death.

• The Charges: Unlike Chavez, Plasencia has pleaded not guilty to charges including conspiracy to distribute ketamine and altering or falsifying records.

• The Allegations: Federal prosecutors revealed text messages from Plasencia that mocked Perry’s addiction, including one that read: “I wonder how much this moron will pay.” He is accused of administering ketamine to Perry in a parked car and teaching the actor’s assistant how to perform the injections.
