Jonathan Diamandis

Jonathan Diamandis is a Canton-area man who has known Michael Proctor since middle school — a friendship of roughly 30 years. He was called by the defense in Trial 2 to authenticate a group text chain among Proctor and childhood friends, a chain containing messages in which Proctor expressed bias toward Karen Read from the earliest days of the investigation. Diamandis's testimony spanned voir dire and a full jury appearance across Days 24 and 25, covering the text chain's authenticity, its participants, and the content Proctor shared through it.
