Relatives of missing New Jersey nanny Stephanie Parze say they are hopeful she is still alive.

Parze, 25, disappeared on her way home in Freehold on Oct. 30 — and her ex-boyfriend, who was being eyed in her disappearance, hanged himself Friday.

Parze’s sister told The Post by phone Friday, “We’ll keep searching” for her.

She said about 200 people were out searching for Parze in a local park and another location last week.

The sibling declined comment when asked about the suicide of her sister’s former boyfriend, John Ozbilgen, also of Freehold.
