LAREDO - An alleged Zeta cartel hitman is on trial in Laredo. The case lays out the inner-workings of the cartel group along our border.

Extra security is set up around the federal courthouse in Laredo. It's all for the trial of an alleged Zeta hitman. Gerardo Castillo Chavez is the man federal authorities say was behind two Laredo deaths back in 2006. Federal investigators say he gunned down two people at a red light in Laredo. One was a 15-year-old boy.

The case brings to light much more, including what goes on inside the Zeta cartel. It's information that impacts us in the Rio Grande Valley because the Zetas move drugs and weapons through the area.

Last week, several former cartel members testified in the trial against Castillo Chavez. During the testimony last week, one man spoke about a Zeta training camp. He said members were given sledgehammers or machetes and told to kill people who were tied up. It was a way to train the new Zeta recruits on how to kill without hesitation.

Monday morning included testimony from The Laredo Police Department. It included recorded phone calls from confidential sources.
