P/O John A. Shepherd killed BoF

Hello ,

I’m looking for details about the loss of P/O John Adamson Shepherd 41621 , lost 5 June 1940 , 1 Squadron Hurricane , during combat in early morning near Rouen . He’s buried in St Sever cemetary but maybe if someone has studied his casualty file we have the initial crash-site indicated ? This may help to solve a mystery about a Hurricane pilot killed at Bacqueville-en-Caux , date being either 5 or 6 June .

Any help appreciated !
