Thank's guys for your responses.Reading this it's indeed seems unlikely that Liersch was responsible for the Mosquito crash in Wijhe.
The document from the Wijhe archive was created by the author of a book which covers the war years in Wijhe.I will talk to him next week and ask him how he got to the name of Liersch for shooting down the Mosquito.Because on the document he gave no source.
