Federal Jury Convicts Ecuadorian for Threatening to Murder San Antonio Park Ranger

SAN ANTONIO - A federal jury in San Antonio convicted an Ecuadorian national for threatening to murder a federal official, announced U.S. Attorney for the Western District of Texas, Justin R. Simmons.

According to court documents and evidence presented at trial, on or about July 24, 2023, Sergio Renato Tapia, 31, called the San Antonio Missions National Historical Park and left a voicemail that included a violent threat to murder a National Park Service ranger. NPS rangers immediately recognized Tapia's voice and worked quickly with the U.S. Marshals Service to apprehend him on July 26.

NPS rangers had previously encountered Tapia on numerous occasions at Mission Concepcion, a UNESCO World Heritage Site and home to an active Catholic church, citing him several times for unlawful possession of a controlled substance. This week, in front of U.S. District Judge Jason Pulliam, the jury unanimously found Tapia had intentionally communicated a threat to murder a federal official, rejecting Tapia's insanity defense after deliberating for one hour.

The NPS and USMS investigated the case.

Assistant U.S. Attorney Kirk Mangels is prosecuting the case.

This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime.
