Floyd Chambers, father of Adacia Chambers, told reporters the family doesn't have answers but has maintained the daughter he know would never hurt people.
The family of Oklahoma homecoming parade crash suspect Adacia Chambers spoke out on Monday to say the person police claim plowed through dozens of people, killing four, on Saturday is not the woman they know and love.
Speaking to a group of reporters alongside Chambers' boyfriend and aunt in the town of Stillwater, Oklahoma on Monday, Adacia's solemn and red-eyed father, Floyd Chambers, admitted "we don't have answers."
However, the family maintained that the unthinkable act Chambers is accused of committing would be "so out of character" for the 25-year-old.

The family spoke out just as Adacia, who stands accused of multiple counts of second degree murder as well as suspicion of driving under the influence, was standing before a judge in Oklahoma for the first time since the tragedy.
Killed in Saturday's crash were 23-year-old MBA student Nakita Prabhakar, originally from Mumbai, India, and 65-year-old Stillwater residents Bonnie Jean Stone and Marvin Lyle Stone.
The fourth and youngest victim, who was just two years old, was Nash Lucas, the son of a sophomore chemistry student.
Floyd Chambers last spoke out on the situation a day after dozens of people at the annual Sea of Orange event in the town were injured when a car careened into the parade route and sent people flying into the air like rag dolls.
"This is not a hate crime thing that she has done," Mr. Chambers said Sunday. "My daughter is not that person. She's a very caring, loving person. This is just a bad accident. I don't know what happened.
"I don't really know what to say to anybody other than my thoughts and prayers are with the people who lost their lives -- the people who are injured. It's just a horrible thing."
Mr. Chambers also revealed that his daughter had, in the past, spent time being treated for mental illness.
"She had a mental hospital she went to in Wagoner at one time. And they had her for a couple of weeks. I took her to another place when she got out of there," he told reporters.
Police in Oklahoma led Chambers away from her crumpled Hyundai sedan in cuffs, apparently uninjured on Saturday morning.
Meanwhile, Chambers' attorney Tony Coleman said Sunday he can 'absolutely can rule out' alcohol as a factor in the crash and said, instead, his client is mentally ill.
An Oklahoma judge on Monday set Chambers' bond at $1 million as she appeared in court via video link, Reuters reports.
Payne County Special District Judge Katherine Thomas also ordered psychological testing for Chambers.
The murder charges against her can bring between 10 years to life in prison.
Chambers did not enter a plea and a second court date was set for November 13.
