Federal prosecutors have escalated a New Mexico criminal case by filing a superseding indictment charging Wilfrido Saenz, Ignacio Jaramillo, and Ismael Jaramillo with conspiracy to transport noncitizens and conspiracy to kill a witness. The new charges significantly raise the stakes, transforming what might otherwise have been viewed as an immigration-related smuggling prosecution into a case centered on alleged obstruction of justice and witness silencing.

According to the Justice Department’s announcement, the superseding indictment alleges that the defendants not only participated in transporting noncitizens, but also conspired to murder a witness tied to the underlying smuggling matter.

The U.S. Supreme Court has approved a settlement ending the long-running dispute over Rio Grande water allocations among Texas, New Mexico, and Colorado, with the United States also participating in the case. The decree resolves one of the Court’s highest-profile original-jurisdiction water fights and establishes the framework for how water deliveries from New Mexico to Texas will be handled going forward.

The litigation centered on the Rio Grande Compact, an interstate agreement governing allocation of river water.
