About

Jonathan Diamandis testified in Trial 2 that he and Michael Proctor had been friends since middle school and were members of a long-running group chat with other Canton friends. He recognized the exhibit as a portion of that text chain, identified Proctor as 'local user,' and said he had no independent memory of the conversations.

Key Points

  • During voir dire on Day 24, Diamandis identified 'local user' in the group-text exhibit as Michael Proctor, linking the displayed messages to Proctor.
  • Diamandis said the document was a true and accurate record of the texts sent during the period shown, while also testifying that he did not independently remember the conversations.
  • During the admissibility hearing after Diamandis's voir dire, Yannetti quoted passages he attributed to Proctor from the exhibit for identification to argue state of mind and bias. Brennan challenged authentication and argued that Proctor should be confronted before the jury was asked to draw investigative inferences from the messages.
  • Before the jury on Day 25, Diamandis identified the nine participants in a long-running group chat and recognized the exhibit as a portion of that text chain. The exhibit showed 38,777 messages for the period from October 18, 2021, through August 31, 2022.
  • On cross-examination, Diamandis testified that Proctor had never suggested to him that Proctor planted evidence, framed a defendant, or tampered with evidence in this or any other case.
