Originally thought BF had her in boot of car over the weekend ( removed from flat in luggage for the weekend) and left her on the road on his way back on Sunday, but now think differently.
Wondering if someone from the pub caught up with her after Waitrose and offered her a lift home and she invited them back for dinner hence the detour back to Tesco to pick up Pizza.
Went from Tesco to home by car. We are told there is no forsensic evidence of a struggle at home so maybe the reason her coat, bag , keys etc were left is that
a: she left quickly escaping an imminent sexual attack on arriving at home, possibly grabbing the killers car keys and heading to his car but was overpowered and bundled into the car & driven away , although very hard to imagine this going unheard or unseen but could explain why no sex attack occurred. .
The mystery pizza may have fallen out of the bag in the back of the car when driving back from the shops and never actually made it into the house.
b) Or she went back out to the car to find the Pizza and was followed out by the unknown person who then bundled her onto the back seat and drove off with her.
This is assuming the Pizza wasnt eaten.
Truly hope the killer is caught , Jo's family deserve to have justice for Jo. Its heartbreaking .
