The alleged driver of a Ford Escape that plowed through dozens of parade participants and spectators on Sunday appeared to have “no emotion on his face” and accelerated toward the crowd, according to a criminal complaint filed against him. Authorities filed the complaint in the Waukesha County district court on Tuesday, detailing the accounts of several law enforcement officers who attempted to stop the vehicle while it sped toward the annual Christmas parade. At least three officers encountered the vehicle and attempted to stop it, with one firing three shots at it. The alleged driver was arrested on Sunday and later charged with five counts of first-degree intentional homicide. A sixth victim, an 8-year-old boy, died Tuesday from injuries sustained when he was hit by the SUV. The first officer identified as Detective Casey encountered the red SUV as it was driving through the parade’s loading ground on White Rock Avenue, which was filled with participants and other vehicles at the time. “[Casey] observed people jumping out of the way of the red Ford Escape. As the Ford Escape was at White Rock Avenue and East Main Street, Detective Casey stepped in front of the Ford Escape and pounded on the hood of the vehicle and yelled multiple times, ‘Stop,’” the complaint says.
