Less than two years later, and two months before Aileen was born, Diane filed for divorce. Aileen had an older brother named Keith, who was born in March 1955.
Wuornos never met her father, Leo Pittman. He was in prison for the rape and attempted murder of a seven-year-old girl when she was born.
In January 1960, when Aileen was almost four years old, Diane abandoned her children, leaving them with their maternal grandparents who legally adopted Keith and Aileen on March 18, 1960.
