Ok,im now thinking he wouldnt have put her in the river,even in spate it really isnt that big or deep.He wouldnt put her in upstream for fear she was pushed down and got entangled near the town and he wouldnt have dumped her near the town for fear she didnt get washed away.
I feel at this moment shes out in the countryside,hes got a 4x4 and could easily do miles across the counryside just by going through farmers fields and rights of ways etc and never be seen from the road.
He was seen in his 4x4 crunching gears,thats could be the clutch on its way out and that could be the result of going up steep inclines or being stuck and revving the engine out.And again just guessing but if hes expeienced in off road driving i doubt that would happen but,if he was panicking or drunk then his driving would be terrible..
