Erwin Adolf Kurt Cohn (1925-1943)

Erwin Cohn (born 19.10.1925 in Berlin) emigrated in 1938 with his family from Berlin, Germany, where they resided at Detmolder Str. 55 in Berlin-Wilmersdof. His father Alfred (*1884-1949) was a moneylender and a merchant. Alfred and his wife Anna Cohn-Maier (*1894-1979) managed to avoid deportation survived the war. Erwin died in Amsterdam on 04.12.1943. I would appreciate any information as to the circumstances of his death.
