I'm trying to figure out where the 96 minutes starts, it's such a precise number of minutes too, I suppose every minute counts in this new theory.
Let's say the accident happened between 9.38 am and 10.00 am. Immediately, FM bundled up the body and put in the boot, got a shovel from under house or shed, remained in same clothes OR changed clothes and back again after carrying out plan.
9.15-9.30 am - FD left the house. Three pics taken of WT on verandah - 9.37am proof of life pic.
9.37 am to 11.13 am ? (the 96 minutes which doesn't make sense unless she arrived back to house 7 minutes after police arrived.)
Did FM drive down the riding school road after FD arrived back home and after making the 000 at 10.56am?
Police arrived 11.06 am.
Did FM drive off approximately 10.00am and returned around 10.25 am and began the pretend search around the streets?
This gave her approximately 25 minutes to drive down to riding school road or nearby, park the car, carry the body into the bush, dig a hole and cover, returned back to home. Was she dirty, sweaty, disheveled? Did she have time to wash up and change clothes? Did she take shovel back to shed?
Did FM drive off at approximately 10.30am when FD arrived? Returned to house before 10.56am to make 000 call. This gave her around 20 minutes to carry out her plan as above, did she appear disheveled to FD and neighbours?
This isn't correct because she was knocking on neighbour's doors around 10.35 am.
Last option, after the accident between 9.38 am and 10.25 am, FM hid body in roof cavity or in the car? And carried out above plan much later in the day or night? This isn't credible either because the scent would've been picked up around FGM's car or in the house?
Police would've checked all through the house and the cars because of the high incidence of kids hiding in the house or car. They're not going to waste time and resources without completing this search.
I hope this makes sense, please pick it a part because I'm sure I've missed something.
