So, this person that they’re looking for is not the father of the baby, is it? The wording makes it seem like it isn’t the same person.
I wonder if this was a “secret” pregnancy. If a underage girl was pregnant and the family hide it for 9 months, then they couldn’t possibly keep the baby. I also wonder if the “father” is actually not the father.
It wouldn’t be hard to hide a pregnancy right now, staying inside is the expected thing to do. So a teen girl “disappearing” for 9 months wouldn’t even be weird.
