I think the current theory is that she had a lay-over in Munich on her way back to Istanbul. Someone in the last thread found a flight that is literally half the price of other Amsterdam-Istanbul flights that had a 9 1/2 hour layover in Munich. I don't believe she spent the night there. It seems like it was more of a stop on her way back to Istanbul from Amsterdam, and is likely she never left the airport there.
I would also agree, however why is there a span of days missing in the middle? We're talking 2-3 days here. This is a reasonable amount of time that the Ammer (AMS) says she was gone, but has not really been accounted for.
Again, no surprise there are contradictions, but this timeline states:
Jan. 7: Sarai Sierra arrives in Istanbul, rents room.
Jan 15: Goes to Amsterdam and Munich.
Jan 18: Returns to Istanbul.
Jan 19: Skypes with her husband, the last time he speaks to her. Posts pic on Instagram of New York City with tag, Never far from my mind.
Jan. 20: Skypes with her two sons, the last time they talk to each other.
Jan. 21: Due to fly back home. Sends sister instant message saying shes going to take pictures at Galata Bridge before going to airport. Never checks in for flight.
Jan. 22: Husband reports her missing. Turkish authorities release video footage of her eating alone at an Istanbul mall. Its not clear when images were recorded.
Jan 25: Istanbul police organize search with over 260 officers for Sierra.
Jan 27: Husband and brother fly to Turkey.
Feb. 2: Sierras body is found in a rundown section of Istanbul.
Feb. 3: Police say Sierra was killed by blow to the head. A witness claims to have seen a womans hand hanging from a bundle a man was leaving in the area previous night.
Feb. 4: Sierras body moved to an Armenian church in Istanbul.
Also, interesting she skypes with her husband one day and sons the next. That would make it seem like they weren't at the same place or perhaps he was working. Let's not forget there's a 7 hour time difference between IST and NYC.
