According to the station, she issued a statement saying she was 'thankful for the support and prayers' she has received since the crash.

Grainy footage has also emerged showing the moment Chambers' car skids into the crowds lining the street, dragging wreckage along behind it.

Hospital officials had previously said that 34 people were wounded in the crash, with eight of them in critical, nine suffering serious injuries, and another 17 with minor wounds.

Doctors updated that last night, saying five children and three adults remain in hospital with conditions ranging from good to critical, while a total of 44 people were injured.

According to witnesses her Hyundai Elantra was driving up to 50mph before running into a parked police motorcycle and then hitting spectators, throwing some '30 feet into the air like rag dolls'.

Captain Kyle Gibbs told reporters that the critically injured spectators had been flown from the scene by air ambulance.

They were taken to Tulsa as well as to Oklahoma University Medical Center in Oklahoma City.

Among those airlifted to hospital was Madison Atwell, seven, who was planning to attend her first Cowboys game when she was caught up in the accident.

According to Facebook posts by her mother Tasha Thomason Atwell, a U.S. Army soldier, she suffered five broken ribs and a bruised lung.

Tasha also posted that Madison is suffering from a head wound which doctors will now have to staple or stitch shut.

Grieving residents of Stillwater, where yesterday's accident took place, have begun leaving tributes at the spot where Chambers' car hit crowds as they watched the homecoming parade

She wrote: 'My sweet little OSU fan went to Stillwater this weekend to spend some time with her Kay Kay and Gigi and to experience homecoming cowboy style!

'She was supposed to get to go to her first OSU football game yesterday. Instead she took her first helicopter ride as she was life flighted from the homecoming parade in Stillwater to OKC.

'Please send prayers this way for my daughter and I will keep you updated on her condition! Please and thank you!'

Chamber's father has also spoken out to defend his daughter this evening, saying he 'cannot believe' she was involved in the accident.

Floyd Chambers, speaking to The Oklahoman newspaper, said: 'I can’t figure this out. This is not the person that’s my daughter.

'I can’t imagine alcohol being involved. She is not an alcoholic. This is just not who she is. They’re going to paint her into a horrible person but this is not (her).'

Among the injured was Madison Atwell, seven, who suffered five broken ribs, a bruised lung, and a serious cut to her forehead during the accident, and had to be airlifted to hospital

Madison's mother, Tasha, paid tribute to her daughter on Facebook this evening, asking for people to pray for a speedy recovery

Speaking through tears, he added: 'My heart goes out to those people and all of them who are injured. It’s just a bad thing.

'I know this isn’t something that she would have done deliberately I know that she’s not that person.'

Earlier in the day, University officials said: 'The Oklahoma State University Homecoming parade is the most wholesome of events and to have it marred in such a way is incomprehensible'.

Oklahoma State University President Burns Hargis said there had been discussion about canceling the homecoming game Saturday afternoon against Kansas, but it was played as scheduled.

The victims were remembered with a moment of silence before kickoff, and most of the OSU players knelt on the sideline in prayer.

Even as the game began, some of the bodies remained at the scene of the crash less than three blocks away from the stadium.

National Guard troops kept watch as officials with the Red Cross and state medical examiner's office continued their work.

Before kickoff, members of the Oklahoma State Cowboys, who are currently playing the Kansas Jayhawks, were pictured kneeling on the pitch and praying

Hundreds of fans wearing the school's bright orange and black colors were forced to walk by the intersection as they headed to the game.

More than 80,000 people attend homecoming activities at Oklahoma State University, according to the OSU Alumni Association, but it's unclear how many people were at the parade.

Witnesses at the scene were shocked by the incident as it occurred.

'At first we thought it was part of the show,' Konda Walker, a 1991 OSU alumna, told the Stillwater News Press. 'People were flying 30 feet into the air like rag dolls.'

Others first thought that the parade had been targeted with a bomb.

The route takes the groups up along Stillwater's Main Street until it intersects with Hall of Fame Avenue, which leads to the OSU stadium.

Chambers's car came south on Main Street and hit the end of the parade route, according to officials.

Gibbs did not say whether Chambers was visibly drunk, but added that there was probable cause for arresting her for driving while intoxicated.

She was arrested in what appeared to be a t-shirt from her job at Freddy's Frozen Custard and Steakburgers, a picture from the Ponca City News showed.

Officers are now waiting for the results of blood tests to determine for sure whether Chambers was under the influence of alcohol or drugs at the time.

Chambers, who is not believed to be an OSU student, is expected to make an appearance in court on Monday.

Oklahoma State President Vaden Burns Hargis said that the university had thought about not playing their homecoming game against Kansas, but has decided to go on with the game and 'remember' those who had died in the incident.

A moment of silence was held before the game, as supporters posted under the hashtag StillwaterStrong for solidarity.

Despite the heartbreaking scenes earlier in the day, Oklahoma went on to win the game against the Jayhawks 58-10, dominating the game from start to finish.

Kansas were forced to kick on third down during their first possession of the game, before Oklahoma made 70 yards in nine plays to score with their first attacking drive.

Backup quarterback J.W. Walsh ran for three touchdowns and passed for two more before freshman Taylor Cornelius took over late in the third.

It's not the first tragedy to strike events connected to Oklahoma State sports programs.

Ten people, including two OSU men's basketball players, were killed in a 2001 plane crash while returning from a game in Colorado.

Oklahoma State women's basketball coach Kurt Budke and assistant Miranda Serna were among four killed in a plane crash in Arkansas in 2011 while on a recruiting trip.
