WAUKESHA, Wis. — The man police say drove an SUV into a Christmas parade crowd last year killing six people tried to set a humbled and conciliatory tone Monday upon his return to a Waukesha courtroom for his homicide trial.

Darrell Brooks Jr., 40, has been defending himself as is accused of 76 counts, including six charges of first-degree intentional homicide, tied to the Waukesha Christmas Parade tragedy in November 2021. Prosecutors say he drove down the crowded parade route striking participants and attendees. 

Before testimony resumed Monday Brooks, wearing a suit, told Circuit Judge Jennifer Dorow he was sorry about his behavior last week. In the first days of trial, he often interrupted Dorow and was repeatedly moved to an adjacent courtroom. One day, he removed his orange jail shirt while in the courtroom.

“It was a very emotional situation,” he said. “I should carry myself with better respect,” he said, adding his mother didn’t raise him to act like he did last week. He stood and apologized to the court, the prosecutors, the clerks and bailiffs, even news reporters, and anyone else in the gallery last week. (He did not specifically mention victims, several of whom attended the trial).

Dorow thanked Brooks for finally seeming to recognize the need for and value of decorum in the courtroom.

‘It was pure chaos’

Testimony began with Brooks’ cross-examination of Waukesha Police Det. Thomas Casey, the first officer who tried stopping Brooks from entering the parade route. Brooks seemed to try to cast doubt about Casey’s identification of Brooks as the driver or that the honking Casey described as evidence of the driver trying to alert people to danger.
