Cassidy Stay is the sole survivor of a shooting that left her parents and four siblings dead inside their suburban Houston home. She, amazingly, survived her gunshot wound to the head, according to BuzzFeed.
Just three days after the shooting, the 15-year-old addressed a crowd in Houston, thanking the community for their support. She quoted "Harry Potter" character Albus Dumbledore during her speech.
Afterward, the Houston Chronicle reports Cassidy received a letter from J.K. Rowling written in the voice of Dumbledore (in purple ink).
