Matthew Perry’s mother, Suzanne Morrison, and stepfather, Keith Morrison, made their presence known as the fifth and final person charged in their son’s overdose death, pleaded guilty.

After agreeing to a plea deal in August, Jasveen Sangha, dubbed the “Ketamine Queen” by federal prosecutors, pleaded guilty on Wednesday, Sept. 3, to one count of maintaining a drug-involved premises, three counts of distribution of ketamine and one count of distribution of ketamine resulting in death or serious bodily injury, the Associated Press reported.

Suzanne and Keith were present at the court hearing in Los Angeles, marking the first time they attended court proceedings since the announcement of the indictments one year ago, according to the outlet.

Matthew died on Oct. 28, 2023, at 54 years old, after an accidental drug overdose. He was found floating face down in his jacuzzi at his Los Angeles home that night.

An autopsy report previously obtained by PEOPLE revealed that his cause of death was due to the acute effects of ketamine. Drowning, coronary artery disease, and buprenorphine effects, a medication used to treat opioid use disorder, were also listed as contributing factors.

After Perry’s death, his family spoke out in a statement to PEOPLE.

“We are heartbroken by the tragic loss of our beloved son and brother. Matthew brought so much joy to the world, both as an actor and a friend. You all meant so much to him and we appreciate the tremendous outpouring of love,” the statement read.

Prosecutors accuse Sangha of distributing the ketamine that killed Perry. She allegedly distributed drugs to Erik Fleming, an acquaintance of Perry’s, who then distributed them to Perry’s live-in assistant, Kenneth Iwamasa. Prosecutors alleged Fleming was an intermediary between Sangha and Iwamasa.

Sangha, Iwamasa and Fleming, as well as doctors Mark Chavez and Salvador Plasencia, were charged in connection with Perry’s death in August 2024.

In August 2024, Iwamasa pleaded guilty to one count of conspiracy to distribute ketamine causing death, admitting to “repeatedly” injecting Perry with ketamine without medical training, including performing multiple injections on Perry on the day he died.

That same month, Fleming pleaded guilty to one count of conspiracy to distribute ketamine and one count of distribution of ketamine resulting in death,

Chavez pleaded guilty to one count of conspiring to distribute ketamine in October 2024. Plasencia pleaded guilty to four counts of distribution of ketamine in July 2025.
