VIDEO: More than 50 extended family, friends, and strangers gathered at a southside Tucson park Tuesday night to support Las Vegas shooting survivor Savannah Sanchez. Sanchez doesn't live in Arizona anymore, but has deep roots in Tucson. Sarina Mendez, Savannah's sister, told AZ Family her sister is in critical condition and on life support. Sanchez was born and raised in Tucson and moved to California about five years ago for college. She was currently working as an assistant pharmacy store manager.
