WAUKESHA, Wis. (AP) — A person taken into custody after an SUV plowed into holiday parade in Wisconsin, killing at least five people, has been identified as 39-year-old Darrell Brooks.

Police haven’t yet identified the “person of interest” they are holding. But two law enforcement officials briefed on the matter provided the identification to The Associated Press. They spoke on condition of anonymity because they were not authorized to discuss the matter publicly.

Online court records showed a person named Darrell Brooks, with an birthdate making him 39, has two open criminal cases in Milwaukee County. In one case, filed Nov. 5, he is charged with resisting or obstructing an officer, reckless homicide, disorderly conduct, bail jumping and battery. Records show $500 cash bond was posted Nov. 19.

In the other case, filed in July 2020, Brooks is charged with reckless endangering and illegal possession of a firearm.

Investigators are looking into whether the SUV driver who plowed through a Christmas parade in suburban Milwaukee, killing at least five people and injuring more than 40, was fleeing from a crime, a law enforcement official told The Associated Press.

Investigators were questioning the person about an earlier crime, which the official described to AP as an argument involving a knife. The official, who cautioned the investigation was still in the early stages, was not authorized to discuss the case publicly and spoke to the AP on condition of anonymity.
