A bus on its way to a casino crashed north of Sacramento, California Sunday night killing ten and critically injuring at least 30. According to one witness, the bus cartwheeled in the air before rolling into a ditch. Victims were either ejected or crushed in the bus accident.

Police say the bus drifted onto the side of the road for half a mile and then the driver overcorrected, which flipped the bus. The driver was taken to the hospital in critical condition. Police believe he was on medication.

Adding mystery to the bus accident, the bus was without a valid license plate, and it is unclear exactly who owns the bus. The bus was sold over two years ago; it dates back to the 1980s and does not have seatbelts. At least 12 people were ejected in the accident.
