According to the "Daily Mail" reported on September 7, a 19 -year -old Brazilian girl said that she gave birth to a pair of twins last year, but their father was not the same person.

It is reported that the Brazilian girl said in an anonymous interview that she wanted to confirm who the child's father was 8 months after giving birth to a pair of twins, so she decided to do a parent -child identification. She found the most likely man and collected DNA samples, but after two tests, the man's DNA only matched one of the babies' DNA.
