Just FYI someone has made a video named "Toyah's last day" it maps with images where and how she may have driven with times too. They clearly have info we don't, apparently she drove through the intersection from police video at 1:58PM. *
If I go with that time suggestion. It takes 14 min on google maps to get to Wangetti from that intersection. So getting there approx 2:15PM either, met someone or informed someone to meet her there. it takes about 12 min to walk 1km so if she unloaded Indie, started walking from the car. she would have reached the 800m point by 2:30-2:40 either she was on her way back and had already gone up the beach, which I am not sure how long she would go for... or if it happened more suddenly and along the walk an altercation occurred she would have been murdered by 2:40-3PM. If she met someone on the half hour, was a bit early and waited in the car park until 2:30, murdered between 3-315Pm.
Person panics, heads back to the car via cover of shrub/bush along the beach. say back at their car between 3:30-3:45. Planning their next move and what to do. Drove along highway.
Or if the time stamp is between 5:02-5:07 at intersection, that may suggest they may have been walking for a little bit, she was on her way back to the car and was murdered between 4-4:30 PM. Anyway just thoughts. Goodnight all.
