[Icare9]

There are 151 Wilson RAF (and Commonwealth) Air Force deaths in 1944, according to the CWGC website. There are only a handful in Italian cemeteries and none with Wing Commander rank. Even including 1943 when the Salo Republic was formed (to save others searching, it was the "puppet" North Italian "State" following the rescue of Mussolini that remained on the German side after the surrender of Italy) there are a further 129 Wilsons, only one a Wing Commander. I would therefore suggest that the name is incorrect, but as to what his correct name could be, I haven't a clue.
You seem to have more than just the details posted here, do you know a more precise date or where the "murder" happened and who by, or any witness statements? Which towns could he be buried in? How did you obtain the original information about his murder?
