Four days after they disappeared on the way to a gig, authorities found the bodies of five members of the Mexican regional band Grupo Fugitivo Thursday (May 29) near the Texas-Mexico border.

According to Tamaulipas state prosecutors, the five men were kidnapped at about 10 p.m. Sunday (May 25) while en route to a gig in an SUV. Authorities recovered their bodies on the outskirts of Reynosa, a border city plagued by drug cartel violence.

The five victims—Francisco Javier Vázquez, Nemesio Antonio Durán, band manager Livan Solís de la Rosa, Víctor Manuel Garza, and José Francisco Morales—were between the ages of 20 and 40.

Grupo Fugitivo often played at local parties and dances. A post made to the band’s Facebook page Sunday (May 25) indicated they were headed to McAllen, Texas. Surveillance footage confirms the men arrived at a palapa bar in the Rancho Grande neighborhood of Reynoso. However, no footage shows them leaving the establishment. Later, family members reported receiving ransom demands, according to the BBC.
