I suggest to make a list of all MACRS of P38s lost in that time era,
Than try to exclude those where pilots were not KIA. Make a list of KIA members of fighter groups from ABMC.gov and go one by one...there is not so much names, P-38 planes I guess
And then when filtered, buy all possible MACRs, and go one by one and exclude again..
that is the only way how to make a possible hit, if the date is correct...
GOOD LUCK
