Betty was a six-year-old little girl living in a small house with her mother and two older brothers in Milwaukee during the Great Depression. In September 1930, Betty was being stalked by a young man who developed a desire to murder her. Edward Cullen, who was living a traditional lifestyle of nomadic vampires at the time, found him, but decided to wait until he had actually committed the crime before feeding on him.
One week later, the boy climbed into Betty's room, intending to kidnap her. Edward immediately struck, took him away and fed on him, saving the girl.
