A human head and a cardboard with a threatening message from the Sinaloa Cartel for its rival gang, the Jalisco cartel, were found in Mexico's Colima state Thursday.

According to Borderland Beat, police received a call about a human head along Lopez Mateos street in Manzanillo city, a few meters from the neighborhood garden, at around 1 a.m. local time. When the police arrived, they also saw the cardboard that contained a threatening message.

The narco message reads, as translated by Borderland Beat: "This will be the fate of all the turncoats. Just as well for all of the Jalisco gunmen. We already have everyone located. Everyone will end up like this individual. Sincerely, La Barredora of the Cartel de Sinaloa."

Authorities immediately cordoned off the area for the corresponding investigation by the Prosecutor's Office. No other details about the finding were provided.

The Jalisco cartel or the Jalisco Cartel New Generation is currently the Sinaloa Cartel's main rival. The Jalisco cartel is being led by Nemesio Oseguera Cervantes, known by his alias "El Mencho."

On the other hand, Ismael "El Mayo" Zambada and Joaquin "El Chapo" Guzman Loera's four sons, known as "Los Chapitos," were reportedly left in command of the Sinaloa Cartel after El Chapo was arrested and extradited to the U.S.

The Jalisco cartel came out from the Sinaloa Cartel in 2010 after the death of former Sinaloa Cartel capo Ignacio Coronel, known as "Nacho," who was killed by Mexican security forces. Nacho's death resulted in the split into two factions - "La Resistencia" and "Torcidos" - of the Sinaloa Cartel.

The "Torcidos" became what is now the Jalisco cartel, which has since expanded rapidly in Mexico. The Jalisco cartel involves itself in many criminal activities, including international drug trafficking.

Aside From the Sinaloa Cartel, Gulf Cartel Also Beheaded 2 Men in Mexico's State of Nuevo Leon

Members of the Grupo Scorpion, a sub-group of the Gulf Cartel, also left a narco message after they beheaded two men in Mexico's State of Nuevo Leon.

According to the Daily Star, one of the heads was put on top of a tarp containing the narco message in Cadereyta Jimenez city.

Borderland Beat reported that the gruesome scene was discovered in the early morning of Tuesday. Some government employees heading to work noticed a couple of men had exited an SUV on Mutualismo Street and placed large bags and a tarp on the pavement. The men quickly went back inside their vehicle and then drove away.

The employees alerted the police to what they had just seen. When the police arrived, they found the tarp, the heads, and two dead male bodies inside the bags.

The bodies reportedly have signs of being tortured, and there were plastic bindings on each man's ankles and wrists. Both men were said to be beheaded, and one of the heads was placed separately on top of the sign. 

The narco message from the Gulf Cartel subgroup Grupo Scorpion started with a warning to the local police and telling the public that the "problem is not with you nor the consumers [of drugs] nor the government, be it municipal or state."

The cartel named some police officers and then accused them of "charging extortion fees" and selling "crystal." The cartel also said they were not happy "with all the irregularities of the municipal police," so "don't mess with our people because you all are next."

"This is the last call, and the security and tranquillity of Cadereyta Jiminez, NL depends on you all," the cartel concluded.

More Heads and Decapitated Bodies Found in Mexico

Five bodies of men were found inside a taxi in the municipality of Juchitan in Mexico's Guerrero state also on Tuesday.

According to reports, three bodies were decapitated or beheaded, while the remaining two were shot to death. The state police received information about a vehicle with an undetermined number of bodies on a road in Las Cuchillas town, near the federal highway, on Tuesday morning.

In the afternoon, the State Attorney General's Office (FGE) confirmed the discovery of the five bodies, adding that it opened an investigation folder for the homicide of five people.

The bodies were reportedly found inside a white public service vehicle with blue stripes on the Marquelia-Acapulco route. There was no immediate information on a possible motive and who was responsible for the killings.

Last March 31, six human heads and some dismembered bodies were found on a parked car in the municipality of Chilapa de Alvarez, also in Guerrero state.

The human heads were found on the roof of a black Volkswagen Pointer with license plates HCX7649 stationed along Eucaria Apreza Boulevard.

Authorities also discovered eight black plastic bags with dismembered human remains inside the vehicle. Along with the heads and bags, a large poster with an intimidating message was posted beside the car.

Authorities believed that the murdered individuals were victims of drug gang-related violence because of the message written on the canvas that gave a warning against kidnapping and drug selling.
