The suitemates are not POI's in her murder though, not from anything I've seen or read. Indeed, the "she was very social" that was first said by her tanning salon colleagues, that I found on the media thread, was oft repeated, suggesting somebody other than family. The investigation was reported on MSM, as it progressed, to still be working its way out from those closest to her, around Julia's first birthday, over a month after her death, in quotes by a detective who grew up with the girls, graduated with them, knew the family well.
