MORE: How to help victims of Thousand Oaks mass shooting
Hundreds of members of the tight-knit community gathered, lighting their candles, holding hands, embracing each other, their heads bowed in prayer - all to support the city that, at one point, was named one of the safest cities in America.
"You might not know everybody's name but you're there for everyone," said Thousand Oaks resident Sara Willis. "We're Thousand Oaks strong tonight."
"I grew up here. It's a joke that we live in a bubble. But as you can see when it bursts we connect and we rebuild," Willis said.

The tragic turn of events at the Borderline Bar and Grill Wednesday night is almost too much to bear. Thirteen dead, including the suspected shooter, who opened fire on revelers at a country western college event.
"I just started hearing these big pops," said one survivor. "Pop, pop, pop. There was probably three or four. I hit the ground and I look up, the security guard's dead."

As thousands packed the performing arts center for the vigil-hundreds more overflowed into the courtyard nearby. The comfort of being together is what this community needs.
"And everybody's gathered here tonight and my heart is broken," Cormier said. "I've got to believe that we are somehow going to find a way to stop this."
