So after hearing Walt's interview I too have come to my own personal conclusion that this was random. The whole "she went out to meet a guy" makes no sense now considering the timeline. Is anyone aware of how far her brother's place is from her own? If she dropped him off at 11PM, she was then seen buying chips at 1130-ish at the convenience store. This part is important, IMO, because her family has stated that she always has a snack before she goes to bed. So she buys that snack, presumably to go home, then she texts her roommate stating she was with some unknown man, then her car is seen going the opposite direction of her home FOLLOWING that text.(I think? I feel like I remember hearing her car was seen after that Snapchat text.)
Do any of you remember Kelsey Smith's murder? She went to go buy a birthday gift for her boyfriend at a Target and disappeared. They finally caught her killer because security footage showed a blur of a man rush toward her and force her into her car as she was returning to it. I have a feeling that's what happened to Aniah after she left the store.
