I was unable to find a matching identity. I searched the full name, just the last name, and just the first name under exact, fuzzy, and DM Soundex. The closest possibility I found was a girl named Pessa Mindla Zytnicka, but she would've been 23 or older - so she can be ruled out.
We often see the masculine and feminine endings of last names switched (Zytnicki/Zytnicka, for instance)--have you tried searching with "Zytnick*" in the last name field and "P*" in the first name field?
I looked again for Zytnick and did not find any matches in either Exact, DMS, or Fuzzy.
