A federal grand jury indicted four people Wednesday in the illegal transportation of immigrants, the U.S. Attorney Office reported Friday. The jury indicted Pedro Torrell-Matos, 69, on unlawfully transporting immigrants within the United States, U.S. Attorney Walt Green said in a press release.

Three others, David Gazpar-Godinez, Estuquio Orozco-Valazquez, and Simo Cruz-Pena, were each indicted on charges of re-entering the United States with the help of a previously deported immigrant, the release says.

The Baton Rouge office of the U.S. Border patrol, the U.S. Department of Homeland Security and the Homeland Security Investigations are looking into this matter, Green says.

Assistant U.S. Attorney Frederick A. Menner is prosecuting the case.
