NEPTUNE CITY - Friends and family will take to the shoreline in their search for Sarah Stern who was last seen almost a week ago at her Neptune City home.

Sterns father, Michael Stern, said friends, family and volunteers will meet in Ocean Grove on Saturday morning at 8:30 a.m. at the Boardwalk Pavilion Praise on the boardwalk at Ocean Avenue and Ocean Pathway. The search will then spread out to Long Branch, Deal, Allenhurst, Asbury Park, Ocean Grove, Bradley Beach, Avon, Belmar, Spring Lake, Sea Girt and Manasquan to search the water and nearby wooded area for signs of Stern.

Stern said it will be cold so volunteers should dress warmly.

Monmouth County Prosecutor Christopher Gramiccioni said a number of agencies including Belmar Police, the New Jersey State Police Missing Persons Unit, Neptune City Police Department and the National Center for Missing and Exploited Children are all involved in the search for Stern whose car was found parked on the Route 35 bridge between Neptune Township and Belmar last Friday night with the keys inside.

A search of the water of the Shark River Inlet below last Saturday and Sunday failed to find Stern. “We are asking everyone to keep an eye out for this young woman, and report any possible sightings as soon as possible,” Gramiccioni said.

Stern's cousin Lauren Bahr spearheaded the effort to get Stern's picture out on social media. “It’s a very strange situation. Everybody just doesn’t understand. Everybody is worried and concerned,” Bahr said.

Stern is described as a 19-year-old white female who stands about 5-foot 6-inches tall and weighing about 130 lbs. with a medium complexion, long dark brown hair that hangs past her shoulders and brown eyes.

A flyer by Monmouth County Crime Stoppers said it is offering a reward of up to $5,000 for information that leads to the “identification, arrest and prosecution of any suspects” in Stern’s disappearance. But Monmouth County Prosecutor’s Office spokesman said officials haven’t yet determined if there was any criminality involved.

Gramiccioni  said anyone with information about Stern should call the Prosecutor's Office at 732-431-7160 or Belmar Police at 732-681-1700.
