One of the three people killed when a gunman opened fire at an In-N-Out Burger had traveled to Idaho to help expand the restaurant chain. Ashley Garibay was tapped to train new employees away from Stockton, California, where she was based. Her family said she loved her work and called her an “amazing, beautiful soul who loved living life.” “She was adventurous, outgoing, smart and driven, never letting obstacles get in her way,” her family said in a statement Tuesday. “She lit up a room with her bright smile and a laugh that was contagious.”Police have not yet said what led the gunman, identified by police as 24-year-old Chad Williams, to open fire Saturday afternoon at the Twin Falls restaurant. The attack ended when Williams shot and killed himself. Police said they are confident Williams acted alone. Twin Falls police Lt. Steven Gassert said Tuesday that he expected more details to be released later in the day. He didn’t elaborate further.

A candlelight vigil was planned Tuesday night at Twin Falls City Park, and police have opened a center where those who were affected by the shooting could get support and request or collect personal items left at the scene. Flags in the city will be at half-staff until next week. The In-N-Out location opened in late July as part of the California chain’s Idaho expansion. Garibay got her first job at one of the restaurants, and she dreamed of one day managing one of the stores, her family said.
