Yeah, and the sarcasm points to skepticism over the mother's story. Last I checked, sarcastically saying "allegedly" implies that you think it unnecessary, but you're checking your ass over liability. Meaning that you think that that is what happened.
And sarcastically emphasizing "answers" implies that the mother has some secret game besides holding those responsible for the murder of child accountable.
Like, am I fucking crazy for seeing this as filled with malice and hate for the victim?
