Driver may have been fleeing previous incident
Based on video evidence and interviews, investigators' preliminary assessment is that the driver wasn't aiming at specific parade participants but was speeding through the route to flee an earlier incident, multiple law enforcement sources told ABC News.
Authorities scoured social media and other digital platforms associated with the person of interest overnight. At this point authorities have no reason to believe there is any connection to radicalization, extremism or the ongoing debate about the Kyle Rittenhouse verdict, the sources said.
