Four men, two of whom are illegal immigrants, are under investigation by U.S. Immigrations and Customs Enforcement officers after they tried to enter the U.S. through a Border Patrol checkpoint while riding in an Otero County, New Mexico emergency rescue vehicle. Three occupants of the vehicle were dressed in volunteer fire department attire and claimed to be U.S. citizens. Three of the occupants also provided agents with New Mexico driver’s licenses when asked for identification. The men all claimed to be going to Alamogordo, New Mexico, to attend a training session.
