About

Jonathan Diamandis, a longtime friend of Michael Proctor, testified about a group text chain among their Canton high school friends. He identified Proctor as the participant labeled “local user,” recognized his own phone number and a message he had sent, and said the records fairly represented the conversation. He also said he had no independent memory of the text conversations. Diamandis agreed that Proctor shared case details with the group and said he had no independent knowledge of the case at the time. He did not recall whether the information discussed was public. He testified that Proctor had never suggested to him that he had planted evidence, framed a defendant, or tampered with evidence. Asked about Proctor’s firing, Diamandis said he did not know its specific grounds.
