Summary

Iwamasa Obstructs

Prosecutors allege Iwamasa directed “B.M.” to discard ketamine vials and syringes after Perry’s death.
The filing says Iwamasa ordered shredding of a ketamine prescription and a note naming Dr. Salvador Plasencia as the source.
Investigators claim Iwamasa erased records, deleted files and changed passwords on Perry’s devices to hide evidence.
A recorded call with Erik Fleming captures Iwamasa admitting he “cleaned up the scene,” which prosecutors label obstruction of justice.

Summary

Iwamasa Harasses Family

He addressed the crowd at Perry Morrison’s funeral, a move the family called a “cruel joke.”
After Perry’s death, Iwamasa repeatedly contacted the Morrison family, sending songs, a cemetery map, and calling whenever he saw a rainbow.
Court filings show Iwamasa earned $150,000 a year as Perry’s live-in personal assistant and threatened the family with legal action after a promised payout was denied.

Summary

Examiner Rules

The Los Angeles County medical examiner ruled ketamine the primary cause of Matthew Perry’s death, with drowning secondary.
He was found dead at his Los Angeles home on October 28, 2023, after the drug was administered.
The family trusted longtime associate Kenny Iwamasa as Perry’s companion and guardian, despite his lack of medical credentials when he gave ketamine.
