A Brazilian woman who took a DNA test to prove the identity of her daughter's father....

And that would work how?

Until recently DNA paternity testing required samples from both putative parents and the child. These days you can get a less accurate test with samples from just the putative father and the child - it's accurate to 98% plus. The old test is accurate to 99.9% plus.

I am aware of only one other case where the putative mother turned out not to be the mother. It was here in Virginia, the children were born at the UVA hospital in Charlottesville. What a mess.
