The residence of 39-year-old Claudia Benton was broken into by a savage intruder. The mother of two, had been brutally beaten, sexually assaulted, and fatally stabbed. The killer was a man named Ángel Reséndiz who had been illegally boarding trains across the US border from Mexico for over 20 years. He would go on to kill at least nine people, but capturing Reséndiz would prove to be one of the FBI’s most challenging cases. Original music by engel.com/">Kai Engel, Ben Krejci, and Lee Rosevere.
