Victims of the Waukesha Christmas parade attack spoke at a sentencing hearing for Darrell Brooks.
After refusing to answer the judge's questions about any additional witnesses, Dorow determined the defense would rest, and jury instructions would be read ahead of closing arguments.
Brooks is accused of driving into the Waukesha Christmas parade route last year, killing six people and injuring more than 60 others.
Brooks, who has no legal training, is representing himself at the trial. He has repeatedly disrupted the court proceedings with defiant and outlandish behavior.
Judge Jennifer Dorow broke for lunch early Friday after Brooks got into a heated exchange with her for about 30 minutes.
