Joel Arteaga Vazquez, 29, disappeared after his birthday party Wednesday night and municipal police discovered his body before dawn the next day.
Arteaga was running for council on the same ticket as Calera mayoral candidate Rodrigo Saucedo Ramirez, according to the PRI spokesperson in Zacatecas state, Veronica Murua.
“As it was not at a campaign event, one cannot presume it’s a political matter,” she said of Arteaga’s murder, though adding that the PRI would monitor the investigation.
PRI officials don’t know whether Arteaga received any threats prior to the slaying, Murua said.
