Mexican authorities found a total of 19 bodies scattered across the city of Uruapan in Mexico’s Michoacán state on Thursday morning.
Some of the bodies were hanging by the neck from a bridge, while others were dismembered.
The killings appear to be part of a scare tactic by the Jalisco New Generation Cartel (CJNG) aimed at their rivals.
Traditionally Mexican cartel violence has been about the drugs trade.
But experts say the fight could also be over the production and distribution of avocados, dubbed “green gold” in Mexico.
