Really insightful interview. At the end, the sister uses the word about perp as "they", which is interesting. At the beginning, the mom whispers to sister "got to get it right. don't get mad". For as close as the girls all seemed, they had little to nothing to say about the surviving friends. They also had little to say about E and X. It was very stoic concerning E, X and surviving roommates. The interview seems like they were trying to draw someone out and emphasized that they are not working with police.
