MEXICO CITY—A former prosecutor and local police official was arrested Tuesday in connection with the grisly decapitation of a mayor on Oct. 6.
Officials in the southern state of Guerrero confirmed that Germán Reyes was arrested on charges of homicide for the killing of Alejandro Arcos just a week after he took office as mayor of the state capital, Chilpancingo.
The arrest was shocking, because officials had previously blamed the killing on a local drug and extortion gang, and Reyes was formerly employed as special prosecutor for Guerrero state, a high-level position.
The implication was that Reyes—who is also a former military officer who, according to his official resume, retired with rank of captain in the military justice system—had somehow worked in collusion with the gang. The mayor’s body was found in a pickup truck, with his severed head placed on the roof of the vehicle.
