Erik Fleming is "regretfully sorry" after being sentenced in connection with Matthew Perry's death.

Fleming, an acquaintance of the late Friends actor, is one of five people charged after his death aged 54 in October 2023, having source ketamine from Jasveen Sangha the so-called Ketamine Queen before giving the drugs to Kenneth Iwamasa, Perry's live-in assistant.

The drug counsellor has been sentenced to two years in prison pleading guilty in August 2024 to one count of conspiracy to distribute ketamine.

Fleming has also been sentenced to three years of supervised release and a $200 penalty.

Prosecutors claimed that Sangha and Fleming sold Perry 51 vials of ketamine, and Iwamasa subsequently injected the actor with at least three shots of the drug.

The actor died from the acute effects of ketamine, and five defendants were subsequently charged with offences related to his death.

Following his sentencing this week, Fleming told Extra that if he could talk to Perry's family, he would tell them: "I'm regretfully sorry and I wish I could take it back."

He also wrote a letter last month to the judge before sentencing, in which he claimed he "felt overwhelmed with grief and shame" after hearing about Perry's death.

In the letter obtained by Extra, he said: "I knew what I had done and understood how much pain his death would cause to the people who loved him.

"To Matt's family, I am very sorry for my inexcusable behavior in this case. I take full responsibility for my criminal acts.

"I hope my sentence provides some measure of justice and peace for everyone who loved Matt."

He admitted to having met Perry "a few times" and knowing "about his struggles with substance abuse".

Fleming continued: "I will accept my punishment with humility and spend the rest of my life working to become worthy of forgiveness.

"I am just beginning a long process of reckoning and atonement for my poor choices in this case.

"I procured ketamine for Matthew Perry because I wanted the money and because I thought I was doing a favor for a friend, I never contemplated the worst possible outcome."

Elsewhere in the note, Fleming admitted "this grievous failure will haunt [him] forever", while insisting his letter isn't meant to "minimise" any responsibility".

He added: "To the contrary, I recognize my role in a profound tragedy. It is something I must live with every day.

"Going forward, I want to be the best person possible, to help others whenever I can, and to show over time that this horrible mistake does not define who I am as a human being."
