FREEHOLD TOWNSHIP — The parents of missing township resident Stephanie Parze vowed to find her as an investigation continued into her disappearance last week.

The 25-year-old was last seen on Wednesday about 10 p.m., according to the Monmouth County Prosecutor's Office. Investigators have expanded the search into Staten Island.

Parze's parents called police after they could not reach her via phone at her late grandmother's house , where she had been living, prosecutors said. Her car was found by police at the house, along with her phone, purse, and the shoes that she wore Wednesday night, prosecutors said.

Her parents, Edward and Sharlene Parez, said they are unaware of anyone who would want to cause harm to their daughter and said the “unknown” of what happened to Stephanie is "driving us crazy." They urged their daughter to stay strong, keep fighting and vowed to find her.

“They’re going to find you. I’m going to find you,” Edward Parze said during an appearance on CNN Headline News on Tuesday.

A GoFundMe page was created to assist the family.

"This latest crisis has taken place at a time when the family has already been struggling," organizer David Mound wrote on the page.

A law enforcement source told told ABC 7 Eyewitness News that a cell phone belonging to a “person of interest" triggered a search around Staten Island's Long Pond Park, a 91-acre park not far from Route 440 and the Outerbridge Crossing.

The Monmouth County Prosecutor's Office confirmed on Wednesday that the search for Parze has extended to Staten Island and is ongoing in the area of Long Pond Park. A spokesman would not say what investigators are looking for. There is no danger to the public, according to the spokesman.

The Prosecutor's Office asked anyone with information about Parze's whereabouts, or anyone who recently has had contact with Parze, to call their office at 732-431-7160 ext. 7032, or Freehold Township police at 732-462-7908.
