I read it as the packages sat in the mail room for a week. That could be up to the mail room personnel to put it in mailboxes, someone could be on vacation, any number of things. So the psychiatrist did not ignore, you cannot ignore something you have no knowledge of. Also, if they sat there a week, and police just got them Monday, then Fox has the dates wrong. Who knows if they were there a week or only over the weekend.
Since there is a gag order, we must be cautious of leaked info, even though that is all we have right now.
Don't forget the news of suspicious packages arriving Monday - while everyone was watching defendant in Court, right?
