One of the scenarios is that she was attacked by someone, who first searched te coat and threw it away when it was no longer of interest. Rode away on her bike with the backpack, went through the bag at a quiet location, threw it away in the bushes and dumped the bike in the pond to hide dna and fingerprints.
Person may live near the park, or may have taken the bus. OR belongings may have been dumped as a red herring and the assault happened elsewhere.
Or.... we don't really know at this time.
The police has published two pictures of Anne. One dates from a few months ago, she is wearing the green coat plus a bag with a leather strap.
The other picture is the selfie Anne sent when she was soaking wet during her trip. As far as I can see, she is wearing the backpack, but the one strap that is visible on the left is almost the same colour as the coat.
