Identified victims of Las Vegas massacre

At least 58 people were killed and 527 were injured after a gunman opened fire Sunday night at a country music festival opposite the Mandalay Bay Resort and Casino on the Las Vegas Strip before killing himself, authorities said. • These are the names and stories of those whose identities were made public Wednesday.

Andrea Castilla: On the weekend of the Route 91 Harvest festival, Ms. Castilla was celebrating her 28th birthday in Las Vegas, where her sister Athena lives. She posted photos from the country music festival — the girls in cutoff shorts and cowboy boots, their arms around their boys. Ms. Castilla was a makeup artist at Sephora in Huntington Beach, Calif., and loved making people feel good about themselves. "Living life to the fullest," her Instagram caption read. Andrea Castilla was holding hands with her sister when she was shot in the head, according to a GoFundMe page created by her aunt, Marina Parker.

Pati Mestas: Ms. Mestas loved Jason Aldean, so when he started performing Sunday night she left her friend Dana to move to the front of the stage. Dana made it out alive, friend Isa Bahu said. Ms. Mestas, 67, originally from Pomona, Calif., did not. She was hospitalized in critical condition and died Tuesday. Bahu met Ms. Mestas through an ex-girlfriend, but they quickly became close and he eventually hired her to work at his Shell store in Corona, Calif. For about a decade she ran the deli, where he said she charmed customers with creative sandwich combinations and homemade sauces. In a Facebook post, cousin Tom Smith said Mestas was also "a true and dedicated Christian."

Austin Meyer: Mr. Meyer was celebrating his 24th birthday and his upcoming anniversary with his girlfriend on Sunday, Mr. Meyer's sister Veronica told KSBW-TV. Mr. Meyer moved to Reno, Nev., from Marina, Calif., to start classes at Truckee Meadows Community College. His sister said he had dreams of opening his own auto repair shop. Mr. Meyer, 24, previously worked at Main Event Transportation, a limousine service company in Monterey, Calif.

Carrie Parsons: She adored country singer Eric Church. And when Ms. Parsons saw him perform in Las Vegas on Friday night, she took a selfie with a friend from the audience with Church visible on the stage in the background and captioned it, "Night made!" Less than five days later, another friend shared that photo on Church's Facebook fan page. She wanted him to know that he'd lost one of his biggest fans. "My good friend Carrie Parsons lost her life in the route 91 harvest shooting Sunday," Carolyn Farmer wrote. "She loved your music." Ms. Parsons, of Seattle, was originally from Bainbridge Island, Wash., and worked as a manager at Ajilon, a staffing agency in Seattle, according to her LinkedIn page.

Brett Schwanbeck: Mr. Schwanbeck, 61, a grandfather of five and a retired big-rig truck driver from Bullhead City, Ariz., felt most at home in the wooded outdoors, said his fiance, Anna Orozco, who was with him at the Las Vegas country music festival. "He was a fun-loving, hard-living man," she said. "He enjoyed life, and he'd help out anyone who needed help." Both grew up in the small Arizona town of Ash Fork, and Orozco had known him since her childhood. Their wedding was scheduled for January.
