Authorities announced on Thursday that the bodies of five musicians from the Mexican regional music group Grupo Fugitivo have been discovered in Reynosa, a northern city along the border with Texas.
The group, known for performing at parties and clubs, had been missing since Sunday. According to Tamaulipa state prosecutors, the musicians were kidnapped around 22:00, while they were on their way to a performance venue in an SUV-type car.
The discovery of their bodies on the outskirts of Reynosa has led to the arrest of nine suspects, believed to be members of a faction of the Gulf Cartel, which maintains a strong presence in the city.
While the authorities have not yet revealed the motive behind the killings, they have not denied local media reports suggesting that the bodies were burned.
Grupo Fugitivo performed Mexican regional music, a genre that includes styles such as corridos and cumbia.
Young artists sometimes pay homage to drug cartel leaders, often portrayed as Robin Hood-type figures.
It is not clear whether the group played such songs or if the artists were simply victims of the rampant cartel violence that has eclipsed the city.
But other artists have faced death threats from cartels, while others have had their visas revoked from the United States under the Trump administration's accusations that they were glorifying criminal violence.
The last time the musicians had contact was the night they were kidnapped, when they told family members that they were going to the event. After that, nothing else was heard about them.
Their disappearance caused unrest in Tamaulipas, a state long eclipsed by cartel warfare. Their families reported the disappearances, called on the public for support, and people took to the streets in protests.
