Milwaukee County District Attorney John Chisholm has launched an investigation into what he called the “inappropriately low” bail set for Darrell Brooks, Jr., the suspect in the deadly Christmas parade attack in nearby Waukesha, Wis. Sunday afternoon.

Brooks, who faces five counts of first-degree intentional homicide, was freed after posting $1,000 bail even though he faces serious felony charges in two different open cases in Milwaukee. In the most recent, he allegedly “ran [the victim] over with his vehicle” in what proved to be an ominous foreshadowing of the horror he allegedly inflicted just days later.

“The bail recommendation in this is not consistent with the approach of the Milwaukee County District Attorney’s Office toward matters involving violent crime,” Chisholm said in a news release, “nor was it consistent with the risk assessment of the defendant prior to setting of bail.”
