LAS VEGAS (AP) - With her smooth skin and wavy, honeyed hair, Elena Caro was celebrated as a beauty by her husband and teenage daughter, who often told her that she didn't need cosmetic surgery.
But at 42, Caro wanted firmer skin and a younger figure, so she secretly booked an appointment with a medical office recommended by a close friend.
The quest for perfection might have ended her life, police said.
Caro was found walking the streets of Las Vegas in agony Saturday after buttocks enhancement surgery that authorities say was performed by two Colombian nationals in the back room of a tile business.
She was pronounced dead minutes later at North Vista Hospital in North Las Vegas. Her cause of death was not immediately determined, pending toxicology tests and an investigation.
Ruben Dario Matallana-Galvas, 55, and Carmen Olfidia Torres-Sanchez, 47, were arrested hours after the surgery for investigation of murder, police said.
The husband and wife were being held without bail at Clark County jail pending a court appearance on Tuesday. It was not immediately clear if they had lawyers.
Las Vegas homicide chief Lt. Lew Roberts said backroom clinics can be found across Sin City. But he said there hadn't been any deaths involving unlicensed physicians in at least six years.
"The tragic thing about this case is that this isn't an isolated incident of somebody going to an unlicensed alleged medical facility," he said.
Matallana-Galvas and Torres-Sanchez had purchased airplane tickets to return to their native Columbia on April 22 but were trying to catch an earlier flight at McCarran International Airport when they were arrested, police said.
Neither suspect had a license to practice medicine in Nevada, officials said. Matallana-Galvas told police he was a homeopathic doctor in Colombia.
Under questioning, he also told detectives he injected Caro with a gel substance, and she was able to walk away from his office after the procedure, according to a police report.
However, Elizabeth Flores, an aide to Matallana-Galvas, told police he had called and said something had gone wrong, and Flores had her husband drive him and his wife to the airport, the police report said.
Caro's daughter, 17-year-old Janet Villalovos, told The Associated Press that her family had begged Caro not to undergo cosmetic surgery.
However, encouraged by a friend who said she had successfully received buttocks enhancement surgery from Matallana-Galvas, Caro booked an appointment for facial Botox injections with him earlier this month.
When no complications arose, Caro quickly scheduled the buttocks surgery. She told only her daughter because she was worried that her husband, brother and sister would be too critical of the procedure and try to talk her out of it.
That morning, Villalovos said, she drove her mother to the makeshift medical office and gave Matallana-Galvas a warning.
"I told them, take care of her, please," Villalovos recalled. "He told me everything is going to be fine. Don't worry."
Villalovos watched the doctor and his wife inject one shot into her mother's buttocks. The sight made her squeamish, so she told her mother she was leaving and would return in four hours when the procedure was done. An hour later, her mother called to say everything was going well.
Later, her mother didn't answer repeated calls, Villalovos said.
When Villalovos returned to the makeshift medical office, it was locked and appeared abandoned. She asked Gilbert Estrada, the owner of Tiles and More, to unlock the door. Inside, the bed, curtains and curtain rods that had filled the room that morning were gone.
Caro was already dead when her daughter began searching for her, according to an arrest report. Onlookers had called emergency officials, who picked her up in an ambulance and took her to the hospital.
Roberts said police do not know how Caro ended up in the remote area but suspect she was dropped off there.
