Would a recording alone be enough to reopen this?

Not on its own. Before drawing conclusions, someone would need to establish where the audio came from, whether the complete original is available, and whether its date, integrity, and context can be independently checked. A short clip or a description of one leaves too many questions open.

Then the specific words would need to be compared with other records from the same period, such as logs, communications, and timelines. If those checks produced credible contradictions, that could support a closer review. The recording is a lead to verify, not proof of what happened.

There’s a difference between asking for a preliminary examination and calling for a whole new investigation. A preliminary check could establish whether the recording is authentic and what order it actually refers to. A broader investigation would need something more: reliable evidence that changes or materially challenges the established account.

So the useful question is not just whether the audio sounds convincing. It’s whether independent material confirms its origin, meaning, and relevance to the timeline.
