Reba gets robbed<br>Reba is walking down the street. She gets mugged. Her purse is taken and her watch. She tries running after them. She cannot catch them and they get away.
The robbers get away from Reba by running away.

The robbers never had to run. They could have driven off or rode bikes in order to escape. I think the system assumed that, since Reba ran that the robbers did also.
