James Keith McElveen
Prosecution forensic audio expert who authenticated enhanced covert restaurant surveillance recordings in all three trials.
About
McElveen is the authenticating expert for the prosecution's central covert-recording exhibits across all three trials. His qualification and testimony supplied the technical chain of custody and the methodological foundation required for admission of the Dolce Vita and Matsuri enhanced recordings. The archive record benefits from his three appearances because they document how the prosecution's exhibit foundation for the same underlying recordings was established, challenged on evolving cross-examination themes, and maintained across successive proceedings, including the resolution of a late-production discovery dispute in the third trial.
