The fourth day of the trial of former Missouri City police officer, Blademir Viveros, saw emotional testimony and a field trip outside the courtroom to see the mangled vehicles involved in the crash. The state and defense rested their cases after the families of the three victims delivered emotional testimonies. The trial is set to continue on Monday, with closing arguments expected shortly after noon. Prosecutors allege that Vivivos was driving 107 mph when he was responding to an emergency call without his lights and sirens on. The crash killed three people, including a mother and her 16-year-old son, and a prisoner in the back seat of his cruiser.
