Remembering Rebecca Wingo, Aurora victim

Rebecca Wingo, a 32-year-old mother of two, died in the Aurora, Colorado theater shooting. "We want Rebecca to be remembered for the loving, giving, brilliant soul that she was," her mother Shirley Wygal tells Anderson Cooper.

Rebecca had worked in the Air Force for 11 years and was going back to school. "She wanted to work with foster children who are aging out of the system and have no where to go," Wygal says.

Her best friend Kate Wodahl describes Rebecca as "vibrant" and says that everybody was drawn to her. "She was always there for anyone that needed her, all the time," Wodahl tells Anderson.

Wygal says that Rebecca's daughters who are five and nine don't understand permanence. "Even if the 9-year-old understands that mommy died, she can't imagine that mommy's never coming back," she says.

"It's important to remember how somebody lived their life, not just how their life ended," Anderson told Wygal and Wodahl.
