The "Roar" heard round the world: Remembering Olivia Wise

Sixteen years is not a long life, but it was time enough for Olivia Wise to inspire millions of people. She died last week after battling brain cancer. But while she was fighting the disease she recorded a cover of Katy Perry's "Roar." It became a viral hit on the internet, and people around the world learned about Olivia's story. For the first time, Olivia's mother and sister sat down with Anderson to talk about the Olivia only they knew.

You can help the Liv Wise fund reach its goal of raising $250,000 to help children fighting cancer.
