The first degree murder trial begins today for the man accused of attacking a 20-year-old woman as she went for a run in Brooklyn in July of 2018.

Cristhian Bahena Rivera’s trial is being held in Davenport. Investigators say video shows Rivera’s vehicle following Mollie Tibbetts, a University of Iowa student, as she went for a run in her hometown. Authorities say Rivera confessed to the crime and led police to Tibbett’s body, which he had covered with stalks in a cornfield. Rivera worked at a dairy farm near Brooklyn. The farm’s owners say Rivera used a different name on his job application. Rivera’s defense attorneys have said he was in the country legally.
