After 15-year-old Cassidy Stay tragically lost her parents and four siblings in a shooting, she quoted Dumbledore from the Harry Potter series at the service — and a month later, J.K. Rowling wrote Cassidy a letter as Dumbledore. Cassidy's uncle shot her family members  in their home after he wasn't told where he could find his ex-wife, and Cassidy reportedly survived by pretending she was dead. During the service, she spoke and quoted Harry Potter and the Prisoner of Azkaban, saying, "Happiness can be found even in the darkest of times, if one only remembers to turn on the light. I know that my mom, dad, Bryan, Emily, Becca, and Zach are in a much better place and that I'll be able to see them again one day."
