Three are dead and numerous others injured after a car plowed into a crowd at the Oklahoma State University homecoming parade.
The Stillwater, Okla. mayor said as of late Saturday morning there were three dead, two in critical condition and 27 injured.
Witnesses on Twitter said a sedan crashed into people lining the end of the OSU homecoming parade route at a high rate of speed. The 25-year-old woman driver of the car was arrested by police and charged with DUI.
Photos on Twitter showed multiple medical helicopters landing near the site of the incident.
"Oklahoma State University is saddened by the tragic parade incident earlier this morning. Our thoughts & prayers are with those affected," the school tweeted out on Saturday.
Dave Kapple of Houston told the Stillwater News Press that he and his son were about 10 feet away when they saw the vehicle barreling into the crowd.
"We heard somebody scream, `Look out!.' (He) plowed through a police motorcycle, and then a crowd of people," Kapple said. "People were flying everywhere."
Konda Walker, from Anchorage, Alaska, was attending the festivities ahead of the homecoming game between Oklahoma State and Kansas.
"At first we thought it was part of the show," Walker told the News Press. "People were flying 30 feet into the air like rag dolls."
