Las Vegas, July 29 : An autopsy report has determined that the death of a woman who died after receiving a buttocks enhancement injection in a makeshift medical office was accidental.
Clark County Coroner P. Michael Murphy told The Associated Press Thursday that 42-year-old Elena Caro died from an adverse drug reaction. He said the autopsy does not preclude criminal charges.
Ruben Matallana-Galvas and Carmen Torres-Sanchez of Colombia face charges of murder and practicing medicine without a license in Caro's April death.
Authorities allege the husband and wife were running a cosmetic surgery business in the back room of a tile store when they injected Caro's buttocks with a gel substance.
Caro was found roaming the streets in agony hours after the injection. She was taken to a hospital, where she died. AP
