Authorities in Sunnyvale have identified Isaiah Joel Peoples, 34, as the driver who appeared to deliberately strike a crowd of pedestrians on Tuesday night, sending eight of them to the hospital.
Several of the victims have life-threatening injuries, according to officials.
The Associated Press reported that Peoples' mother said her son is a "model citizen" and Army veteran of the Iraq War who suffered from post-traumatic stress disorder.
The FBI is helping Sunnyvale's police handle the investigation.
