STILLWATER, Okla. – Investigators continue to try and piece together what made an Oklahoma woman drive into a crowd of people during a homecoming parade.
On Oct. 24, thousands of people were lining the streets of Stillwater to enjoy Oklahoma State University’s annual homecoming parade.
Shortly after 10:30 a.m., the parade took a tragic turn.
In all, authorities say four people were killed and 46 others were injured in the crash.
Among the fatalities were a 2-year-old boy and two former members of the OSU faculty.
Immediately after the crash, Chambers was taken into custody for suspicion of driving under the influence.
However, those charges were upgraded to four counts of second-degree murder.
Now, investigators are trying to figure out what caused the crash to occur.
Law enforcement officials at the crash site said she appeared to be “under the influence of a prescription medication.” Authorities also say that Chambers’ co-workers stated that she “appeared to be in a daze” prior to the crash.
Chambers’ attorney, Tony Coleman, says he doesn’t believe his client was under the influence at the time of the crash. Instead, he says he believes that mental illness may have played a role.
According to the affidavit for a search warrant, Chambers may have been suicidal at the time.
“Just prior to the incident, Ms. Chambers was heard stating she was “Going home forever,” the search warrant affidavit reads.
“Upon booking, defendant admitted to having a history of suicidal attempts and admitted to booking staff that she was suicidal at the time of the incident but not at the time of booking,” the probable cause affidavit reads.
During the search of Chambers’ home, officials seized a Bible with handwritten notes inside, a laptop computer, a hard drive, a tablet and an Xbox One.
Authorities say they are also looking into Chambers’ car for clues related to the seconds leading up to the crash.
Chambers’ next hearing is set for Nov. 13.
