STILLWATER, Okla. - Investigators are still trying to determine exactly what happened the moments leading up to a deadly crash at the Oklahoma State homecoming parade.
Homecoming weekend at OSU includes a number of well-loved traditions, including the 'walk around.'
Like thousands of other Stillwater residents, Adacia Chambers participated in the event.
Family members say they saw no red flags less than 24 hours before she is accused of driving through a crowd of spectators, injuring 46 people and killing four others.
“The girl I seen (sic) on Friday night, the girl that was with me for the walk around, was happy, funny, caring. Even the friends I was with that she met for the first time made that same comment,” said Lynda Branstetter, Chambers' aunt.
After the walk around, Adacia's boyfriend, Jesse Gaylord, says she went back to work at Freddy's Frozen Custard.
Around midnight, she came home.
"She just seemed at ease, then she told me she couldn't really sleep. I don't know if she got more than an hour or two of sleep that night," he said.
On Saturday morning, Adacia Chambers left for work as usual.
She arrived at the restaurant around 9 a.m. and her attorney says she left work an hour later, around 10 a.m.
Tony Coleman, Chambers' attorney, says for the next 30 minutes, his client can't remember what happened.
"The look on her face, there is a very blank, almost lifeless look in her face," Coleman said.
Police say around 10:30 a.m., Chambers headed south on Main when she reached Hall of Fame.
At that point, she allegedly slammed into a police motorcycle, veered around a barricade and drove into the crowd of spectators.
Her car finally came to a stop after hitting a light pole in front of Hasting's Entertainment.
Investigators say they have been able to create the timeline leading up to the crash, but they are now looking at something else.
Chambers' car is equipped with a crash data recorder, which can tell police how fast she was driving, if she tried to slow down or if she ever hit the brakes.
