This is as good a time as any to make the observation that there seems to be one friend of AS, in particular, who seems to be doing a lot of image/narrative crafting on SM and in MSM interviews -- and even quite recently, in spite of being asked to "keep it quiet". She seems dead set on casting herself (and the BFFs) in a sympathetic light, and on casting as much doubt as possible on TS. Additionally, any time someone mentions the possibility of involvement by someone other than TS, she's there to redirect attention back onto TS.
It's odd to me, because IMO if she truly does know more than everyone else, and if she truly cares about justice for her friend, she'd STHU and let LE do their job. There's plenty of time for clout chasing once the case is solved.
