Another possibility is that 'Brian Peppers' is a name that has been misidentified or is part of some sort of urban legend or false information that has circulated as a 'true story'. Without more details, it's difficult to accurately determine what the so - called true story might be.
I'm not entirely sure who 'Brian Peppers' specifically is in a widely known 'true story' context. There could be many people named Brian Peppers. It might be a name specific to a local event, a family story, or something relatively unknown to the general public without more context.
