The sixth charge is for victim Jackson Sparks, an 8-year-old boy who was walking in the parade with his 12-year-old brother Tucker, who was also injured in the crash, The Associated Press reported. If convicted, each charge has a life sentence.

Investigators allege that Brooks, 39 turned into the parade route in Waukesha on Nov. 21 and drove his vehicle side-to-side without touching his brakes, hitting dozens of people. It was announced later that night by police that five people had died.

Brooks was arrested after he knocked on someone’s door asking for help calling for a ride.

Earlier this month, Brooks had been charged with a different case on Nov. 5, in which he used his SUV to run over the mother of his child on Nov. 2, according to FOX6 News Milwaukee.

The same day he was charged, Brooks received a pre-trial safety risk assessment, according to a document FOX6 found. The form, filed by a JusticePoint investigator, is used to aid the court in deciding bail. The assessment deemed Brooks as a Level 4 risk for failure to appear, as well as a Level 6 risk for new criminal activity, meaning he is more likely to not appear and commit a new crime. The document also said that Brooks is on an active hold with the Waukesha County Sheriff’s Office and that he is diagnosed with a “serious and persistent illness in which he is not receiving treatment for.”

Court Commissioner Cedrid Cornwall set Brooks’ bail low despite concerns. Brooks was able to post bail on Nov. 19. Brooks’ current bail is set at $5 million, with a preliminary hearing on Jan. 14.

Waukesha County District Attorney Susan Opper filed five counts of first-degree intentional homicide against Brooks on Nov. 23, for victims ranging in age from 52 to 81.

Willy Medina, a spokesman for the state public defender’s office, which is representing Brooks, declined to comment on the added count.

Brooks’ alleged motive remains unknown. Investigators have said he was fleeing the scene of a domestic dispute when he turned into the parade but police were not pursuing him. He was free on $1,000 bail in a Milwaukee County case earlier in November in which he is accused of intentionally striking a woman with his car.
