Lee, who has suffered from depression and bipolar disorder, admitted she committed adultery and became pregnant while married with two children. When the baby arrived stillborn, she did not seek medical help but instead panicked. She placed the newborn in a plastic container and left it for several days in the back of her sport utility vehicle.
Lee said she feared being convicted and executed, but prosecutors said they didn't intend to seek the death penalty. Still, she could have faced life in prison without parole.
Police found out about the baby when a couple who had been lined up to adopt the child called authorities. Lee told police what happened, but Stern's autopsy concluded the baby was suffocated.
