The New Mexico Department of Justice has investigated fuel prices in San Juan County under prior Attorneys General. Investigations were inconclusive, but there was relief at the pump for a brief period. “We just want to be assured that San Juan County is paying what’s fair at the pump,” said Commissioner Lanier. “With limited competition between brands, it is worth checking out.”
Deputies responded to reports of a shooting and located 18-year-old Elihue Vialpando, who had sustained fatal gunshot wounds. A second victim, Jack Chavez, suffered a gunshot wound to his leg and was transported to San Juan Regional Medical Center for treatment. Witness statements revealed Vialpando brandished a pistol and fired rounds earlier in the night, but based on the timeline of events and witness statements, did not support actions by Thomas Vigil.
The suspect escaped during Sunday afternoon church services. He asked to go to the bathroom and never returned, immediately initiating a count and search of the facility.
This is the first escape in the 31-year history of the jail-based treatment center.
