You would be looking for a letter written in 1982 and sent to McNear from Hawaii.
It was a revelation that he ‘visited his mother in Hawaii’ in that timeframe. I only unearthed that information yesterday.
Prior to that, the water was muddied by Martha Trowbridge and Orly trying to turn Barrington Hughh Anthony Smith from Jamaica, who had a name change in 1974, into zero.
Surprise, surprise, there is a record of zero’s visit to Hawaii around that time. Only McNear knows when that was for certain, seems she still had the letters he wrote her.
She would be the key as to IF zero was in Hawaii at the time of the accident. Might explain why you couldn’t obtain what you were looking for...a mugshot would be nice.
