Matthew Perry's assistant found him unconscious “at least” twice before he died

Matthew Perry's former personal assistant Kenneth Iwamasa admitted that he found the “Friends” actor “unconscious” several times in the weeks before his death.

Iwamasa administered the lethal ketamine injection that killed Perry on October 28 and recently pleaded guilty to conspiracy to distribute ketamine resulting in death.

In his confession, obtained by Page Six, Iwamasa admitted that he injected Perry with “significant amounts of ketamine” in the days before his death, totaling about “6 to 8 injections per day.”

The former assistant said he found Perry “unconscious in his apartment at least twice” in October.

On the day of Perry's death, Iwamasa said he injected the actor at around 8:30 a.m. and then again at around 12:45 p.m.

But just 40 minutes later, Perry allegedly asked Iwamasa to prepare his hot tub and “shoot [him] “Do something big,” which means another dose of the dissociative anesthetic.

They were the actor's last words.

After giving Perry his third ketamine injection of the day, Iwamasa went to run some errands – and hours later found the actor lying face down in his hot tub.

Last week, authorities announced that Iwamasa, Erik Fleming, Dr. Mark Chavez, Dr. Salvador Plasencia and Jasveen Sangha – known as the “Ketamine Queen” – were all charged in connection with Perry's death.

Although the “17 Again” actor was taking ketamine legally to treat his depression, he began abusing the drug in September 2023.

Prosecutors allege Plasencia supplied the actor with liquid ketamine and lozenges and even showed Iwamasa how to inject it into Perry.

Plascencia is said to have involved Chavez in the plot in order to obtain more ketamine and profit from Perry's known addiction problems.

“I wonder how much this idiot is going to pay,” Plascenia Chavez is said to have texted.

In total, the “Fools Rush In” actor is said to have paid doctors around $55,000 for the drug.

Perry also purchased the drug through Fleming, who acted as a middleman between the actor and an unnamed drug dealer.

According to court documents, all of the ketamine administered to Perry on the day of his death came from Fleming.

Fleming pleaded guilty to one count of conspiracy to distribute ketamine and one count of distribution of ketamine resulting in death on August 8.

Chavez also agreed to plead guilty to one count of conspiracy to distribute ketamine. He faces up to ten years in prison.

Plasencia, for his part, pleaded not guilty to one count of conspiracy to distribute ketamine, seven counts of distribution of ketamine, and two counts of altering or falsifying documents or records related to the investigation.

He faces 10 years in prison for each ketamine-related charge. Additionally, he could serve up to 20 years in prison for each count of falsifying documents.
