MILWAUKEE (WTAQ) - A Milwaukee woman withdrew an insanity plea Thursday, after she was accused of killing a pregnant woman and stealing the fetus, so she could claim to have a baby of her own.

34-year-old Annette Morales-Rodriguez had pleaded not guilty by insanity on the advice of her previous lawyers.

But a court-appointed doctor did not find enough evidence that Morales-Rodriguez was insane at the time of the incident. And a judge said an expert opinion sought by a previous defense lawyer would not stand up to scrutiny.

So Thursday morning, Morales-Rodriguez changed her pleas to not guilty on two charges of first-degree intentional homicide.

Authorities said she killed 23-year-old Maritza Ramirez-Cruz last October – and the victim’s full-term baby boy died when he was grabbed from the womb by the defendant.

Morales-Rodriguez told authorities she was desperate to have a child, because she and her boyfriend could not conceive one.

The woman’s trial is scheduled to begin on Monday in Milwaukee County.
