Paternity Dispute: Just do a DNA Test, Right? Not In This Case....

Here's some crazyness to brighten your day. A couple is separating, and the man wants parental rights for their child -- the one he was at the birth for, the one who calls him papa. She is saying, "No Dice, he may not be the father, I was sleeping with someone else during the period of conception." You think, no problem -- see which man the child's DNA matches. Case solved. Right? Except, here, the woman was apparently sleeping with the purpoted father's identical twin brother.

Oops.
