In the early hours of August 8 2019, police responded to an emergency call, where they found seven dismembered bodies on Industrial Boulevard, a few steps from the Petróleos de México pedestrian bridge. Minutes later, authorities located another six bodies elsewhere on Industrial Boulevard, at the intersection with Libramiento Oriente, in the La Cofradía neighborhood. In the México neighborhood, bags with the remains of three people were found. Finally, around 5 in the morning, motorists alerted the municipal police authorities to report three more hanging bodies. Near the bodies was a banner with a message threatening presumed members of
Los Viagras, and claiming that the violence is not "war against the people."
Background Before the massacre, the Jalisco New Generation Cartel had announced its arrival in the municipality with a series of narcomantas threatening rival groups. Months later, an ambush carried out in a wooded area of the municipality, among members of criminal organizations, left ten dead and three injured, setting off the alarms of the state authorities. ==Investigation==
