MEXICO CITY (AP) -- A Mexican human rights official says 13 people are missing following the withdrawal of vigilantes from a violence-wracked city in southern Guerrero state.
The disappearances add to confusion surrounding the intervention by so-called "community police" in the city of Chilapa earlier this month.
Chilapa is being fought over by two rival drug gangs, the Rojos and the Ardillos.
The vigilantes took over the city on May 9, supposedly to end the violence. But some residents claimed they worked for one of the two gangs.
The head of the Guerrero state human rights commission said Tuesday that 13 people had been reported missing between May 9 and mid-month, when the vigilantes withdrew.
Ramon Navarrete said residents appear to have waited for the vigilantes to withdraw before filing police reports.
