STILLWATER, Okla. – A woman suspected of driving under the influence plowed into a crowd Saturday during the Oklahoma State University homecoming parade, killing four people – including a toddler – and injuring dozens more after a collision that sent some spectators flying through the air.

Stillwater police Capt. Kyle Gibbs said the woman’s Hyundai Elantra struck an unoccupied motorcycle of an officer who was working security at the parade, then went into the crowd. She was taken into custody, and Gibbs said investigators were awaiting the results of blood tests to determine if she was impaired by drugs or alcohol.

Oklahoma University Medical Center and The Children’s Hospital announced in a statement Saturday night that a 2-year-old was the latest to die from injuries from the morning crash. Five children and three adults remained hospitalized with conditions ranging from good to critical, officials said.
Gibbs had said earlier that three people were killed and 34 people were taken to the hospital, including eight in critical condition.

Police said Adacia Chambers, 25, of Stillwater, was arrested on the DUI charge.

Oklahoma State President Burns Hargis said there had been discussion about canceling the homecoming game Saturdayagainst Kansas, but it was played as scheduled, with OSU winning 58-10.
