STILLWATER, Okla. - Hospital officials say a 2-year-old has become the fourth person to die after a woman suspected of driving under the influence plowed into an Oklahoma State University homecoming parade crowd.

The child's death was reported Saturday evening in a news release from OU Medical Center and The Children's Hospital in Oklahoma City. The child died at The Children's Hospital.

Police have said a car driven by 25-year-old Adacia Chambers struck an unoccupied motorcycle of an officer working security at the parade Saturday in Stillwater. The vehicle then went into the crowd.

In addition to the four deaths, more than 30 were injured. They included eight who were airlifted to hospitals with critical injuries.

Chambers was taken into custody on the DUI charge.
