In the past few days, Hudspeth County Sheriff's Department deputies and their families have received threats to stay off the Rio Grande. Sheriff Arvin West told ABC-7 Thursday morning, before departing for Houston that the Mexican military is behind all of this. Sheriff West said, "There is no doubt in my mind -- from the first time going back to a couple of years ago and every time in between --- it's the Mexican military. In a nutshell, everybody's been trying to tell everybody that they were here...they've been here ...[and] they come here quite often, regularly."
