Mexican police on Thursday found nine bodies hanging from a bridge, seven more hacked to bits, and another three dumped nearby in what they said was a gang turf-war massacre that left 19 people dead, including at least one woman.

Near the hanging bodies was a banner bearing the initials of the notoriously bloodthirsty Jalisco drug cartel and a threat to a rival gang, prosecutors in the western state of Michoacán said.

“Be a patriot, kill a Viagra,” the banner read, referring to the other cartel, the Viagras.

Down the road from the seven cut-up corpses were three more bodies, for a total of 19 people killed in the grisly feud, authorities said.

“Certain criminal gangs are fighting over territory, to control activities related to drug production, distribution and consumption,” state attorney general Adrián López Solís said. “Unfortunately, this conflict results in these kinds of acts that justifiably alarm the public.”

Two of the bodies were half-naked and hanged by their necks from the bridge, López Solís said. One of the dismembered bodies was a woman.

Mexico security analyst Alejandro Hope said the slaughter was also meant to send a message to authorities.

“This kind of public, theatrical violence, where you don’t just kill, but you brag about killing, is meant to intimidate rivals and send a message to the authorities,” Hope said.

“This kind of cynical impunity has been increasing in Michoacán.”

Mexico set a record for homicides in the first half of 2019, with 17,608 — up 5.3 percent compared to the same period in 2018.
