The name of the town was Porvenir, or “future.” In the early morning hours of January 28, 1918, 15 unarmed Mexicans and Mexican Americans were awakened by a state-sanctioned vigilante force of Texas Rangers, U.S. Army cavalry and local ranchers. The men and boys ranged in age from 16 to 72. They were taken from their homes, led to a bluff over the Rio Grande and shot from 3 feet away by a firing squad. The remaining residents of the isolated farm and ranch community fled across the river to Mexico, where they buried the dead in a mass grave. Days later, the cavalry returned to burn the abandoned village to the ground.

These, historians broadly agree, are the facts of what happened at Porvenir. But 100 years later, the meaning of those facts remains fiercely contested. In 2015, as the centennial of the massacre approached, a group of historians and Porvenir descendants applied for and was granted a Texas Historical Commission (THC) marker. After a three-year review process, the THC approved the final text in July. A rush order was sent to the foundry so that the marker would be ready in time for a Labor Day weekend dedication ceremony planned by descendants. Then, on August 3, Presidio County Historical Commission Chair Mona Blocker Garcia sent an email to the THC that upended everything. Though THC records show that the Presidio commission had been consulted throughout the marker approval process, Garcia claimed to be “shocked” that the text was approved. She further asserted, without basis, that “the militant Hispanics have turned this marker request into a political rally and want reparations from the federal government for a 100-year-old-plus tragic event.”

Four days later, Presidio County Attorney Rod Ponton sent a follow-up letter. Without identifying specific errors in the marker text, he demanded that the dedication ceremony be canceled and the marker’s production halted until new language could be agreed upon. Ponton speculated, falsely, that the event was planned as a “major political rally” for Beto O’Rourke with the participation of La Raza Unida founding member José Ángel Gutiérrez, neither of whom was involved. Nonetheless, THC History Programs Director Charles Sadnick sent an email to agency staff the same day: “After getting some more context about where the marker sponsor may be coming from, we’re halting production on the marker.”
