Sandra García Pérez took the oath of office Monday to become the mayor of the Muncipalidad de San José. She had been vice mayor.
The position became vacant when Johnny Araya Monge, mayor for the last 22 years, resigned to pursue his campaign for president.
Ms. García said that education and solid waste disposal would be priorities for her.
Meanwhile, the Partido Acción Ciudadana came out with an email attack on Araya saying that the municipality is deeply in debt although that has not been made public.
Another email under the name of Epsy Campbell, an Acción Ciudadana leader, was critical of Rodolfo Hernández, the presidential candidate of the Partido Unidad Social Cristiana. The email said that he was a puppet of former president Rafael Caldera. Hernández, a physician, was director of the Hospital Nacional de Niños for 12 years. She is a potential candidate, too.
