STILLWATER, OK - What started out as a joyful Saturday at a homecoming parade for Oklahoma State University, ended as a day of sadness.
"People were here having fun, and literally they don't know what hit them. it just came 40, 50 miles an hour. they were speeding through the crowd of people," said witness Tracy Epperson.
Gail Lamb, another witness said, "You just don't expect that on a happy day at a parade."
Stillwater Police say, 25-year-old Adacia Chambers, plowed into the crowd killing four people and injuring at least 40 others. Police believe she had been drinking.
Three of the victims were adults, who died at the scene, and a 2-year-old boy, who later died at a hospital.
"Our thoughts and prayers are with the family of those who died and those who are injured," said Stillwater mayor, Gina Noble.
An Oklahoma State student, who was hit by the car, Kailey Carter said, "The car hit me as it was stopping, and then I flew over some strollers."
Reportedly, 17 victims remain hospitalized Sunday; four in critical condition.
"Oklahoma State homecoming parade is probably one of the most wholesome happy events in the country. And to have it fouled like this, and these victims, this terrible tragedy," the university's president, V. Burns Hargis said.
