N.J. Teen’s Death on Train Tracks Was Ruled a Suicide — But Her Parents Still Believe Someone Killed Her

More than 11 years after 18-year-old Tiffany Valiante was found dead on railroad tracks in New Jersey, her parents are still searching for answers. Authorities ruled her death a suicide after she was struck by a New Jersey Transit train on July 12, 2015. But Stephen and Dianne Valiante have never accepted that conclusion, believing their daughter may have been killed and her body placed on the tracks. In a recent interview with PEOPLE, the grieving parents revealed how the unanswered questions have continued to shape their lives.

On the night she died, Tiffany had attended a graduation party for a cousin near her family’s home in Mays Landing, New Jersey. She later returned home to shower and change. At around 9:15 p.m., her best friend and the friend’s mother reportedly confronted her over allegations that she had used the friend’s debit card without permission. The confrontation left Tiffany visibly upset, according to accounts cited in the investigation. A surveillance camera captured her walking away from the family’s driveway at 9:28 p.m. She was wearing a headband, a T-shirt, white shorts and shoes.

Less than two hours later, Tiffany was struck by a train. When her body was found, she was no longer wearing the shorts or shoes seen in the surveillance footage. The circumstances surrounding her final movements and the condition in which she was discovered have remained central to her family’s concerns. Her parents have repeatedly questioned whether the original investigation fully examined the available evidence before authorities ruled her death a suicide.

The case has gained renewed attention through the eight-part podcast series Cruel Summer: The Violent Death of Tiffany Valiante. The series examines evidence and personal messages recovered from Tiffany’s phone and laptop, including exchanges that offered additional insight into her relationships and the difficulties she was experiencing before her death. Dianne told PEOPLE that seeing messages the family had not previously known about was heartbreaking. However, the newly examined material has not publicly established that Tiffany was murdered, and the official ruling remains disputed by her family.

For Stephen and Dianne, the uncertainty has become an enduring source of pain. Dianne explained that the family’s search for answers has left them questioning people and situations they might once have trusted. She continues to believe that someone may know more about what happened and hopes renewed public attention will encourage witnesses to come forward. The family maintains that Tiffany would not have taken her own life, pointing to the plans she had made for her future.

Before her death, Tiffany had recently graduated from high school and earned a volleyball scholarship to attend college. Her parents remember her as a strong-willed young woman who spoke her mind and wanted to help others. More than a decade later, they remain determined to uncover the truth about her final hours. While authorities have continued to stand by the suicide ruling, Tiffany’s parents say they will not stop seeking answers about the daughter they lost at just 18 years old.
