Michoacán law enforcement authorities have detained all members of the Ocampo (Mexico) police force as part of an investigation into the murder of Fernando Ángeles Juárez, a candidate for mayor in the township of roughly 24,000 people.

“Ángeles' murder was followed by an unusually dramatic confrontation — but his killing is far from unusual in a country that has seen scores of politicians murdered in the past year,” NPR reported.

According to NPR, Ocampo Police Chief Oscar González is suspected of ties to organized crime.
