When did Jeff York die?

There is no publicly available information about a person named "Jeff York" who has passed away. To help me find information, could you please provide more context? For example:

* Is there any other information about Jeff York? (e.g., his age, profession, location, etc.)

* Are you looking for information about a specific Jeff York? (e.g., is he an actor, a musician, or a person from a particular city?)

* Where did you hear about Jeff York's death?

The more information you provide, the better I can assist you in finding the information you need.
