Looking for the location of chimpanzee Sebastian (Switzerland)

[Kr0xxx]

Heyo!
My name is Kr0xxx and I work as an assistant zookeeper with the primates at Aalborg Zoo, Denmark.
We are currently home to 3 Western Chimpanzees (Pan Troglodytes Verus). And I am attempting my hardest to locate the older brother of My (8 years old), and son of Jutta (48 years old).
His name is Sebastian and he is somewhere in Switzerland. That is all I know.
If any swiss people/general zoo nerds know any further that would mean a lot! (ZTL screenshot of the three possible places)

Jutta (Left) and, My (Right)

I reckon that there is a decent chance that @ShonenJake13 might know the answer - so have tagged him into this thread

Thanks for the tag TLD, @Kr0xxx Sebastian should be at the Walter Zoo.

@ShonenJake13 Thank you. But acording to their website. Sebastian is not part of their troop(s) of chimpanzees

Their website is fairly out of date. The zoo now has 15 chimpanzees according to a friend, and only 12 are listed on the website…
