On May 12th, rangers responded to a disturbance at the Xanterra Parks and Resorts employee pub in Yellowstone and arrested a Xanterra employee claiming to be Manuel Trevino III for disorderly conduct and being under the influence of alcohol to a degree that he posed a threat to others. At the Yellowstone jail, Trevino’s fingerprints were scanned into the Joint Automated Booking System (JABS) system, which automatically runs fingerprints against an existing nationwide database. A ranger saw that Trevino’s prints matched those of Rigoberto Barajas, a previously deported alien with an extensive criminal history and many known identities. Barajas was in possession of false identification documents which were later found to have been used in his employment verification process to work in Yellowstone, an action that is in violation of a federal law on document fraud (8 USC 1324(c)). NPS special agents worked with Immigration and Customs Enforcement and the Social Security Administration Office of the Inspector General during the investigation to confirm that Barajas was an alien who had illegally reentered the United States. Barajas was successfully prosecuted, and, pursuant to a plea agreement, was sentenced in September to 41 months in prison for illegal reentry of a previously deported alien into the United States (considered an aggravated reentry offense due to the type and severity of his past felony convictions) in violation of 8 USC 136(a)(1) and (2) and (b)(2). The JABS system went online in Yellowstone last January.
