That is not an unusual event. She goes to the bar, has one drink and tells Clark to go now or find another ride home.

She clips him with the right side of the vehicle. She is not sure what happened but believes the car hit his hand or arm with the right side mirror. She doesn't want to confront Clark again and goes home.

This case is not about intent to kill. The evidence will not support a charge of murder. It is an accident that turned fatal.

She is focused on getting home to her three children. For her the argument is over, she is headed home.

necessarily an unusual or catastrophic event.

I don't want to be that guy mumbling into his drink at a bar.
