[2] Internationally, she won two silver medals while competing in teams in three Pan American Games: first along María Fernández and Ofelia Ávila in Indianapolis 1987, and then in Havana 1991 along Alejandra García and Miriam Véliz.

After winning five consecutive gold medals at the 1986 edition hosted in Santiago de los Caballeros, Dominican Republic, she was awarded the 1986 National Sports Prize of Mexico.

[7] Controversially, she also served as president of the Mexican Archery Federation (in Spanish: Federación Mexicana de Tiro con Arco),[1] where she was involved in two major scandals that forced her resignation.

According to the claimant, the travel expenses of the minor had been paid in advance by a state government, but Bretón booked a single room for both alleging budget cuts and, reportedly, asked an accompanying female athlete (with no prior knowledge of the local language nor acquainted with the city) to search for and bring back something to eat at the hotel while she sexually harassed his daughter.

[3] A year later, in October 2005, Bretón was caught by immigration authorities of the United States while trying to secure travel visas for two deli vendors and a friend of her own daughter by presenting them as official coaches of the Mexican archery team.
