Mollie Tibbetts, a University of Iowa student, disappeared while jogging in Brooklyn, Iowa. A massive search ensued, ultimately leading investigators to surveillance footage showing a black Chevy Malibu near her last known location. This led to the arrest of Cristhian Bahena Rivera, an undocumented farmworker, who initially denied involvement but later confessed to killing Tibbetts and disposing of her body. Rivera was convicted of first-degree murder and sentenced to life imprisonment, despite later recanting his confession. The case highlights the use of technology and persistent investigation in solving a complex disappearance.
