stopped at a light, and he pulls up beside me in the other lane. he tells me, i love you so much, gorda. i'm so happy. and that was the last time i heard his voice. >> reporter: the light turned the green and everything changed. >> he was in front of me and i'm driving and i feel somebody hit me from behind. at first i thought it was an accident. >> reporter: a sudden jolt, then another. >> i feel another hit. and i said, what the hell? and i looked in my rearview mirror, and it was frances. >> reporter: bill's wife. they'd spoken by phone but never met. bonnie said she never saw frances on the road before she felt those jolts, never taunted her with her middle finger, as frances claimed. now, bonnie said frances wasn't just chasing her. she was actually repeatedly ramming her cadillac escalade into the back of the range rover. >> i started screaming because she wouldn't stop hitting me.
