This is somewhat of a short story mainly due to the speed which the research was resolved.
This medal pair, awarded to 48645 Douglas Royston Higgins, was handed into the South Australian Police, who forwarded them to the Directorate of Honours and Awards and finally they came to me. Higgin's full name is distinctive so it didn't take long to follow him through the electoral rolls and Ancestry family trees. The family trees showed he had a son but listed as a private entry.
The most difficult piece of the puzzle was finding the son's name. Once that was resolved came the realisation the son died only last year. The funeral notice provided all the details I need to contact the family. A positive outcome for less than an hour of research.
The retuned medal tally is now 2883.
