I would say yes in a booth but not necessarily the suv ! I remember reading that the owner of the suv came forward and would have thought the vehicle was searched for dna ? Was the vehicle found to be exceptionally clean !?I think if you evaluate it in “theory” take her phone as not having left Heworth till 10am. She’s not at home. Looks like she’s left in a rush - pots in the sink, toothbrush on the kitchen drainer (but bed made) she can’t have travelled far. It must be an option to travel north south east and west from Claudia home and establish how far you have to move to connect to a different sector. Then you’d find where - then it’s just when. 6am there’s no call from her, 8.23pm on the 18th is your last text - there’s your window. She must have been put in a vehicle at some point - when? The suv parked across the pavement at 9.01pm on the 18th has to be a favourite - did it just park up in Heworth and then the following morning move. She could have been in a boot - upon disposal the perp found her phone and switched it off
I also believe the police know the owner of the car next to the suv
