'It just mowed everybody down': Witness

Witnesses told the Herald Sun they saw a white Suzuki hit a number of pedestrians crossing over Flinders St, one of Australia’s busiest intersections.
"The driver was speeding, it was horrific, I can't believe it," one witness claimed.
"There was people's bodies on the ground. I didn't know what to think (sic).
Witness Sue who works at a doughnut shop in the area told 3AW she saw a white car approach the intersection where a lot of people were crossing the street at the time.
‘We turned to the left… we see this white car as it approaches the intersection – it just mowed everybody down… people are flying everywhere,” she said.
“Then we hear this thump…thump… the car must’ve hit the tram stop in the middle.”
