Another mayoral contender killed in Mexico, 6th politician murdered this year ahead of national elections

Prosecutors in southern Mexico said Wednesday that a mayoral candidate was killed in the Pacific coast state of Guerrero, one of a half-dozen local politicians murdered so far this year ahead of the June 2 national elections.

Tomás Morales was hoping to become mayor of the violence-wracked city of Chilapa, Guerrero.

The ruling Morena party had not formally named Morales as candidate, but he was considered a top contender in the race.
