Summarize the conversation that takes place between John and Ev outside of the Randall home.

John goes to the Randall residence and runs into Ev, Karen's stepmother, outside. Even though she is reluctant to talk at first, she ends up sharing details about what happened prior to Karen's death. She explains how she found Karen collapsed in the car, drove her to the hospital, and heard her say that Art had done this. Ev also says that $300 had been taken, presumably to pay Art for the abortion. John says that Art never accepts payment for abortions and charges only a minimal fee for lab work.
