We've had a spate of people go missing in New Jersey this past year, and it's horrifying for the loved ones — for the family and friends.

It seems like yesterday when Danielle Imbo of Mount Laurel and her friend Frank Petrone Jr. went missing. They were out on Valentine's Day night in Philadelphia in his pickup truck — and it's the last time they were seen. That was nearly 12 years ago.

It gets to me every year when the anniversary comes and goes — we spoke to the family on the air. So I'm pleading with you, as 2016 comes to a close, look over these pictures, see if anyone looks familiar — and if they do, please contact the authorities immediately.

There's more info below the gallery as well.

The missing

The gallery above details missing persons cases going back to 2010 — 15 in all. But State Police are tracking dozens of such cases — going as far back as 1959.

Teen still missing: Among the missing is Sarah Stern, a 19-year-old  aspiring artist who disappeared earlier this month. Her 1994 Oldsmobile was found parked on the Route 35 bridge over the Shark River Inlet in the early morning hours of Saturday, Dec. 3. No one has heard from her since, and father Michael Stern has said he's at a loss to explain why she would want to leave.

“We are gonna keep searching and we are not giving up till Sarah is home. Our hearts are heavy with sadness because Sarah is still missing and everyday she is not found it get harder to face each day without her. Everyone loves Sarah,” Michael Stern recently told New Jersey 101.5.

Help find this Marine: The list also includes Lance James, a Marine who has been missing since Dec. 2. That night, James’ family has said, the 29-year-old went to the Hide-A-Way Tavern but was escorted out after some sort of altercation with a fellow patron. Police asked him to leaev, though his wallet and phone were inside, his family has said.

”Lance never made it home that night. It’s almost like he completely vanished. He did not show up for work, call out or pick up his pay check. Lance did not reach out to anyone by any means, neither friends or family have heard from him since.  Lance does not own a car,” his sister wrote on a GoFundMe page trying to raise reward money for information that might lead to his return.

Not his body: David Cohen was reported missing by family members on April 22, 2015 and was last seen alive on April 20 at the Red Lion Motel, located on US 206, Southampton Township, State Police said. He was traveling from out of state to visit a friend located in Lacey Township. Cohen checked into the Red Lion Motel for the evening and no contact with him has been made since then, according to police.

Police were searching for Cohen when they came upon a decomposing body in the woods of Burlington County weeks later.  It ultimately turned out to be that of Angelina “Angel” Cocuzza, a 61-year-old woman who went missing from her Lumberton home more than three years prior.
