Washington State Patrol said Saturday that the driver of the white Jaguar sedan, a 27-year-old man, is in custody. Police have not offered a motive. One woman is in critical condition and the suspect has been arrested.
Riots broke out in Seattle after the death of African-American George Floyd during his violent arrest by a white police officer in May in Minneapolis.
