Has there been an official or highly reliable release of the text messages? Because the time of the last text would be important. Likewise I really don't trust that SM saw Karlie at 5:30 am because so much of the timeline was lied about early on it is difficult to trust any of it.No she couldn't have run away 2-3 hour before. MG says she last saw KG at 5:30 5:45 (again the time changes) That is when she texts the boyfriend. He asks "is she okay?" and MG says "no not really" And then supposedly falls back asleep at 5:45 am
Then MG says she woke up at 7:15 (initially she said 6:30) and KG was "gone" Not missing. Gone.
Even if we believe every word of whatever version we choose to believe, Karlie could have left right around 5:30 which would be 2 hours before witnesses reportedly saw a woman walking down the road.
