Video: Isabel Perez, sole survivor of mom Mayra Nunez's murders, continues miracle recovery

Isabel Perez, nicknamed Bella, has beaten tremendous odds simply by being alive.

Back in February, she was shot by Mayra Nunez, her mom, in a burst of violence that ended the lives of her siblings, Nivek and Eric. Nunez later took her own life, and Bella wasn't expected to survive.

Somehow she did, however, and this week, her family invited the media to marvel at her progress. See photos and videos below.
