J.K. Rowling sends Texas massacre survivor a care package after she quoted Albus Dumbledore

Harry Potter creator J.K. Rowling has contacted the teenage survivor of a shooting rampage that claimed the lives of her parents and four siblings at their Houston home.

Rowling's publicist said the British author sent Cassidy Stay a letter and package, but the contents were private.

Speaking at a public gathering days after the shootings last month, the 15-year-old girl paraphrased a quote by Albus Dumbledore, headmaster of the Hogwarts school of wizards from the Harry Potter books.

"Happiness can be found even in darkest of times, if one remembers to turn on the light," she said.

The teen survived a head wound by playing dead.

Her aunt's ex-husband, Ronald Lee Haskell, faces multiple capital murder charges in the shootings.
