Tommy was driving home from work and was changing a CD in his CD player. He did not see that the traffic light had changed from green to red before he made it into the intersection. As a result, he did not see Susie crossing in the crosswalk and struck her with his car. When Tommy realized what he had done, he stopped the car immediately and got out to help Susie. When he saw that Susie was bleeding profusely, Tommy went back to his car to use his cell phone to call for help.

While Tommy was calling for help, Alexis was driving down the same street. Because Alexis was talking on her cell phone she did not see Susie in the roadway and ran her over, breaking her legs.

A statute in this jurisdiction makes it a misdemeanor to run a red light.

In an action against Tommy and Alexis, what theory or theories, if any, might Susie assert against each defendant?
