The coroner's office identified those killed as Las Vegas residents Brent Allan Hallett, 47, and Maris Mareen DiGiovanni, 30. Hallett was stabbed in the back and DiGiovanni died from a chest wound, authorities said.
DiGiovanni was part of the Best Showgirls In Vegas modelling and talent agency, according to Cheryl Lowthorp, who runs the business. She said two others with the agency were among the wounded and a third escaped without injury.
According to the police report, some performers said he made them feel uncomfortable when he approached for a photo and one backed away. One woman said he stabbed her in the back, then stabbed DiGiovanni.
Anna Westby, who suffered a punctured lung, said she and Caytano were with DiGiovanni when Barrios attacked them.
"I'm screaming, asking everyone for help," she told KLAS-TV. "He caught up to me, and he stabbed me in the back and then he ran off."
Best Showgirls In Vegas provides models and showgirls for various promotional events from restaurant openings to airport greetings. In her 12 years operating the agency, Lowthrop said the models have pretty much gone day to day "without incident."
"This is a safe job, there are cops everywhere," Lowthorp said. "No place is filmed more than the Las Vegas Strip."
The police report said Barrios was covered in blood when he was arrested. Officers seized a large, long-bladed knife, the report said.
Barrios told one victim "sorry, man" before stabbing him in the back and also said that he hoped police would shoot him, the report said.
It wasn't immediately known whether Barrios had a lawyer who could comment on his behalf. He made his initial court appearance and was ordered held without bail.
Barrios had an address in Los Angeles and told police that he came to Las Vegas two days earlier to move in with a friend who then refused to let him stay at the house, so he packed his things and took a bus to the Las Vegas Strip, according to the arrest report.
