WAUKESHA, Wis. (AP) — The SUV driver who plowed into a Christmas parade in suburban Milwaukee, killing at least five people and injuring 48, was leaving the scene of a domestic dispute that had taken place just minutes earlier, Waukesha’s police chief said Monday.

Police Chief Dan Thompson said there is no evidence the bloodshed Sunday was a terrorist attack or that the suspect, Darrell Brooks Jr., knew anyone in the parade. Brooks acted alone, the chief said.

Brooks, 39, of Milwaukee, had left the site of the domestic disturbance before officers arrived, and was not being chased by police at the time of the crash, according to the chief, who gave no further details on the dispute.

Police said they were drawing up five charges of intentional homicide against Brooks.

He has been charged with crimes 16 times since 1999 and had two outstanding cases against him at the time of the parade disaster — including one in which he was accused of deliberately running down a woman with his vehicle.

On Sunday, a joyous scene of marching bands and children dancing in Santa hats and waving pompoms gave way in an instant to screams and the sight of crumpled bodies as the SUV sped through barricades and struck dancers, musicians and others in the community of 72,000.

The dead were identified as four women ages 52 to 79 and an 81-year-old man. Members of a Dancing Grannies club were among those killed, as was a bank employee.

Mayor Shawn Reilly described the parade as a “Norman Rockwell-type” event that “became a nightmare.”

“It looked like dummies being thrown in the air,” said Nicole Schneiter, who was there with her children and grandchildren. “It took a second to register, like, ‘Is that what we really just saw?’ And then you looked in the road and there were just people laying in the road.”

At least nine patients, most of them children, were listed in critical condition at two hospitals, and seven others were reported in serious condition.
