Call me ignorant but what attracts a small group of Koreans to be in a U.S. Mexico border town to begin with. I am assuming it was not a major Mexican town that attracts U.S. tourists or it would have been named.
Yes, there’s more missing in this story than is in it. Where, why, how, etc? Who are these Koreans? Tourists, missionaries, what?
Reynosa/Hidalgo is a crossing point for illegals into South Texas. Wouldn’t be surprised if they show up on this side of the Rio Grande.
For years I have visited the Rio Grande Valley, as it is called by thousands of tourists (snow birds) every winter. The border towns like Reynosa are large and provide low cost dental and pharmacy services for border crossers. The cantinas usually have live music, drinking, and dancing. And the prices are slightly lower than on our side of the border. It is not hard to imagine these Koreans were soaking up some of the native color.
That said, Koreans will stand out in the crowd there as most tourists are anglo. The way they were caught does not seem to imply that they were involved in antisocial activities, what else can you do when some people wearing uniforms come up to you? Does anyone know what the time of day of this kidnapping was. If after dark than forget what I said about tourists, they were taking a risk, as most of the drug deals, prostitution, Etc. are evening activities.
