An Arizona woman claimed she “blacked out” the moment she hit the accelerator pedal and ran her boyfriend over and doesn’t remember the ordeal despite having visible damage to her vehicle, police said.

Vanessa Santillan was arrested after the bizarre April 21 altercation with her boyfriend in Tempe, AZFamily.com reported Wednesday. Santillan was in the car with her boyfriend when they got into a heated argument that escalated when he exited the vehicle as she came to a stop.

When she honked her car horn, he allegedly flipped her off and continued walking away, appearing to send Santillan into a rage, police said.
