What all of these unlucky women, as well as 430 others in the Mexican city of Guadalajara,had in common was that they had all had medical treatment from a woman called Miriam Yukie Gaona, paying her up to 1,000 a day for the treatment. she said she'd make us look like Barbie dolls, said Ms.Lopez.Howevent Ms.Gaona was a medically untrained ex-dancer who passed herself off as a doctor and treated hundreds of women before she was finally arrested. she claimed to be able to perform cosmetic surgery, but instead injection dangerous chemicals into her victims, leaving many permanently scarred. The Mexican media called her La Matabellas the beauty killer, although her lawyer said ...but she didn't kill anyone-and none of them are beautiful anyway.
