I have shared your theory as well for a long time, however police seem adamant a death has occurred. Going by both FP's timelines, he sent a message at 10.30 and arrived at Benaroon at 10.35. He said the house was about 2 minutes away. When the FM approached AMS it was 10,40 am and AMS could hear the MFC calling for WT. He could have arrived at 10.38. Could the FM have received the msg, taken WT in the car to meet the MFC on some quieter part of Batar Creek road or a quiet offshoot and both given WT a hug and a kiss goodbye,"Wow, you're going to have a lovely trip with ----" got in their cars, her racing back first and then him arriving to go into full act? The FGM never mentioned her daughter taking the car or bringing it back.......... ?
