A south Texas sheriff says a shooting that injured one of his deputies was the first indisputable case of spillover violence from the Mexican drug wars in his County.

Hidalgo County Sheriff Lupe Trevino says the Sunday shootout started when several of his deputies went to investigate a reported kidnapping and drug deal.

One suspect was killed and two were wounded. In all, six people were taken into custody, including the alleged kidnapping victim, and are awaiting charges.

The sheriff says one of his deputies was wounded several times, but body armor probably saved his life.  The deputy is recovering at a hospital.

Trevino says this new chapter in the Mexican drug wars started when Samuel Flores Borrego, the Gulf cartel's reputed second-in-command, was killed in September.

He says that war has now spilled over into south Texas, because there are more cartel members living in Texas now.

It was only a matter of time.  The cartels' war over drug smuggling routes has been getting closer to American soil for some time.  Now it's here.  Now the question is: what will the U.S. government do about it?
