LAREDO (AP) – Federal authorities say a Mexican national has pleaded guilty to charges that he was attempting to lead a group of people across the Texas border when three died after being swept away by rushing waters. Twenty-five-year-old Omar Gonzalez-Herrera of Nuevo Laredo, Mexico, pleaded guilty Monday in Laredo, Texas, to a count of transporting immigrants resulting in death. Authorities say he was to be paid $1,500 to help 14 people cross illegally into Texas near Laredo. U.S. Border Patrol agents encountered the group Aug. 2 after following footprints near the Rio Grande River. They learned that three people were carried away by the current, including a 5-year-old boy. Gonzalez-Herrera faces up to life in prison when he’s later sentenced.
