Tiffany Valiante, 18, has graduated high school and is on her way to Mercy College in New York. Standing 6 feet 2 inches tall, Valiante is a star athlete, earning a volleyball scholarship.

On July 12, 2015, Valiante left her cousin's graduation party. A few hours later, the family learns Valiante has been struck and killed by a train traveling 80mph in a secluded, wooded area just four miles from her home. The death is ruled a suicide by the medical examiner. 

Valiante's family is fighting that ruling over many issues. First and foremost, Valiante had an intense fear of the dark, meaning there was no way she would walk more than four miles in the dark. Her shoes were found more than a mile from her body, yet her feet were clean. A rape kit was not performed on Tiffany’s body.
