The man accused of killing six people and injuring dozens more by ramming an SUV into a Christmas parade last year in Waukesha, Wisconsin, will plead not guilty to his criminal charges by reason of insanity.
Darrell Brooks, the 40-year-old accused killer, has changed his plea from “not guilty” to “not guilty by reason of mental defect or insanity.” Waukesha County court records show that he will undergo a mental evaluation.
