The games of Ghost

[BunnyShoggoth]

I wonder if anyone on the forums is in touch with the relatives of Ghost (Björn Ludwig) who passed away in December 2019? If yes, I would like to ask whether any materials from his unfinished games (such as Collateral Jelly and Once Upon a Crime II: Gumshoe Odd Ventures) survived on his PC and could be made public?

Also, perhaps someone would happen to have the screenies from Once Upon a Crime II that Ghost posted on the AGS forums back in 2008 (the links are all dead now)?

Thank you in advance!!!
