Police in Mexico have begun a search for nine members of polling teams who have gone missing in Apatzingan, a west-central town in Michoacán.
Apatzingan is the historic town in which Mexican leaders met to write the country’s first constitution, but in recent years it has fallen to the will of the Knights Templar drug cartel.
Saturday, three Consulta Mitofsky pollsters failed to return after completing their assignments near Apatzingan even though the 33 other members of the team had.
When it was realized that they had not returned, three more members went looking for them. They also disappeared.
Parametria, another polling firm, also reported three team members missing Tuesday, just before the other pollsters went missing. It is not clear where they were working when they disappeared.
