No ransom demand. No news at all. The official investigation has not progressed in the month since María Esther Aguilar Cansimbe, a young journalist employed by the Diario de Zamora and Cambio de Michoacán newspapers in the southwestern state of Michoacán, disappeared on 11 November. Nonetheless, there are reasons for thinking her disappearance was linked to her reporting and that drug traffickers were involved.
A Reporters Without Borders representative met recently with Aguilar's family and some of her close colleagues.
The epicentre of a federal offensive against drug trafficking launched in 2006, the state of Michoacán is under the sway of such high-profile crime organisations as The Family, a local cartel, and the Zetas, a paramilitary group.
Shortly before her disappearance, Aguilar had covered a local police official's alleged use of violence and abuse of authority. She also covered the detention of two leading members of The Family, one known as "Nineteen and a Half," who was arrested in August, and the other known as "El Bofo" (Fatty), arrested on 30 October.
The Michoacán State Justice Attorney General's Office claims to have written 19 procedural reports since the start of the investigation into Aguilar's disappearance, but her relatives said "no one ever contacted us" and they insist that the case file has just passed between judicial officials in the cities of Uruapán, Zamora and Morelia without any explanation being given.
Aged 32 and the mother of girls aged 7 and 9, Aguilar is the ninth journalist to disappear in Mexico since 2003.
