The tragic incident unfolded as hundreds of thousands gathered on Water Street for the parade, where Doyle's car struck the large crowd around 6 p.m. local time. Injuries were reported for 79 individuals, among them four children, with at least 50 requiring hospital treatment. Doyle, described as a father of three and a former Royal Marine, wept in court as he confirmed his details. He has been charged with seven offenses, including dangerous driving and causing grievous bodily harm.

Prosecutor Philip Astbury described the act as deliberate, indicating that Doyle aimed for members of the crowd as they were attempting to leave the area. Due to the severity of the incident, a judge has kept him in custody pending trial, with hearings scheduled for further proceedings. Legal restrictions prevent the identification of certain victims, including minors. The investigation remains ongoing, involving extensive review of evidence like video footage and eyewitness accounts. The community remains in shock as they grapple with the aftermath of the crash, which cast a shadow over what was meant to be a festive celebration.
