The California Highway Patrol spotted Kumar’s vehicle driving in Oroville the next day and detained the driver, 20-year-old Cassondra Ladawnya Belton for vehicle theft and possession of stolen property. Two other occupants inside the car, a 17-year-old male and a 17-year-old female, were taken into custody with Butte County Child Protective Services.
