“When he made that right turn, that’s when he got really dangerous,” Hickey said.
Angelito Tenorio, a candidate for state treasurer, had just finished parading in the parade and was returning to Main Street when he saw the SUV speeding along the road.
“All of a sudden I heard a loud bang,” said Mr. Tenorio, a city councilor from West Allis, nearby. “Then I heard loud screams and screams. It was very heartbreaking. “
He described a chaotic scene that left him stunned and shaking.
“People were running away, leaving their things behind sobbing,” he said. “When the crowd cleared, it looked like there were people on the ground who could have been hit by the vehicle.”
In a video posted to the city’s Facebook page, the SUV can be seen speeding down the parade route and screams can be heard from the crowd. Then, seconds later, a policeman comes running by, followed by a number of police vehicles as a group of children stop playing.
Peggy Tom, 58, said after the car passed her, she walked down the street looking for a friend, whom she later found out injured.
There were “piles of instruments,” Ms. Tom said, “and shoes.”
Other people walking through the chaotic scene, she added, were shouting the names of lost loved ones.
Don Paul Browne, a city alderman, walked in the parade with the mayor but had already left and did not witness what happened. He said the city is celebrating its 125th anniversary.
