Four years later and the events leading to the death of 35-year-old Pennsylvania resident Tracy Hottenstein are still unknown.
The Cape May County Prosecutor's Office has set up at this year's polar bear plunge hoping someone would provide some much needed information, an idea shared by polar bear plunge guests.
"If there is information to be had, I think it's wonderful to do that this weekend," said Mary Frances Cummings of Norristown, Pennsylvania.
"I hope that if there is information, people will come forward and speak out on the situation."
"I know it appears the investigation is still ongoing and we hope and pray someday the information is received and the case is solved," said Jim McGinness, also of Norristown.
Back at the polar bear plunge in 2009, Hottenstein was last seen leaving the Ocean Drive Bar and Restaurant around 2:15am on February 15th.
Hours later, her body was found near the Sea Isle City Marina.
While her death was ruled accidental and caused by hypothermia complicated by acute alcohol intoxication, four years later the Prosecutor's Office is still trying to piece together the sequence of events leading to her death.
The truck set up on JFK Boulevard hopes to find answers while also providing guests with a reminder to monitor the people they are with.
"Everyone has to do the buddy system and watch out. We teach our kids this from an early age, the buddy system. Unfortunately this happened to this young girl, I would not want to be in her parent's place," said Alexis Tulio of Sea Isle City.
"It brings a sense of responsibility and awareness to people that are down here to have a good time, but at the same time, keep aware not to go too far," said McGinness.
The Cape May County Prosecutor's Office is urging anyone with details regarding the death of Tracy Hottenstein in 2009 to call 609-465-1135.
