(CNN)- As authorities piece together the circumstances regarding how and why an SUV barreled through marchers during a Christmas parade Sunday in Waukesha, Wisconsin -- killing five and injuring dozens -- the suspected driver of the vehicle will make his first appearance in court on Tuesday.

Darrell E. Brooks, 39, is the lone suspect, according to Waukesha Police Chief Dan Thompson. Brooks is slated to appear at 4 p.m. CT and will face initial charges filed, according to the Waukesha County District Attorney's Office.

"We are working closely with the City of Waukesha Police Department to review the matter and decide what criminal charges will be issued," the DA's office said Monday. Police said they would be referring five counts of intentional homicide as well as other charges.

Brooks had been released from jail less than two weeks ago in a domestic abuse case -- on a $1,000 bail that prosecutors recommended and now say was "inappropriately low."
