Stefanie's mother, Stacey Schaffer suffered multiple broken bones and internal injuries. Stefanie, a 22-year-old dancer, sustained life-threatening injuries resulting in both of her legs being amputated.

Stefanie Schaffer's family has since created a GoFundMe page to help cover the costs of the medical procedures for her and her mom.
