The defense is entering a fourth day of testimony at the murder trial of Chicago Police Officer Jason Van Dyke.
Wednesday, jurors heard the initial 9-1-1 call that brought Van Dyke and Laquan McDonald together for what proved to be a deadly encounter.
Truck driver Rudy Barillas made the call after confronting the 17-year-old in a secured truck lot. Barillas testified that the teen tried to stab him with a knife, so he called police.
McDonald was suspected of stealing radios from the truck lot.
Also, Chicago Police Officer Leticia Velez testified that she begrudgingly went to the scene because her partner wanted to go. She described seeing McDonald walking down the street before the shooting.
