THOUSAND OAKS, Calif. (AP) — Barely a year after surviving a massacre at a country music festival in Las Vegas, Brendan Kelly found himself in a terrifyingly familiar scene. Kelly, 22, said he was dancing with friends at a bar in suburban Los Angeles on Wednesday night when the bullets began flying. When the gunfire was over, 12 people were dead, including a Navy veteran who had lived through the deadliest mass shooting in modern U.S. history a year ago. "I already didn't wish it on anybody to begin with for the first time," Kelly said outside his home in Thousand Oaks. "The second time around doesn't get any easier."

THOUSAND OAKS, Calif. (AP) — The mourners gathered to hold hands, to sing and to wonder how one of the safest cities in America could become a killing zone. Hundreds of people gathered Thursday evening to remember the dozen people shot and killed by a Marine veteran at the packed Borderline Bar & Grill the night before. It was a scene of horror enacted in many places around the country in recent months, but never before in Thousand Oaks.

Telemachus Orfanos, 27, survived the shooting at a country music concert in Las Vegas in October 2017, but was among the 12 killed on Wednesday at the bar in Thousand Oaks, California.
