It's possible:
* She is still living. Many artists continue to create and exhibit well into their later years.
* Her death is not publicly documented. Some individuals choose to keep their personal information private, and this could apply to her death date as well.
To find more information, you could try:
* Contacting art galleries or institutions that have exhibited her work.
* Searching for obituaries or death notices in online databases or newspapers.
* Reaching out to her family or close associates (if you have access to their contact information).
I hope this helps!
