It's important to note that:
* Limited Public Information: Some individuals, particularly those not in the public eye, may choose to keep their personal information, including death details, private.
* Lack of Online Presence: If Alfons Heck was not a widely known figure, it's possible that there is little to no online information about him, including his death.
If you are seeking more information, it might be worth trying:
* Searching for German-language sources: As Alfons Heck is a German actor, there might be information available in German-language news archives or biographical resources.
* Contacting German entertainment organizations: Organizations such as German film archives or actors' unions might have information about deceased actors.
Keep in mind that finding information about someone's death, particularly if they were not a very public figure, can be challenging.
