I think you mean the very first video? with Greg, Parents, and brother (Chris) that was whooshed very early on.
that's very true.
I know I am being very single minded in my belief in the BF's guilt. I am wondering if this text has been leaked by the police on purpose.... I think he started out late to Sheffield, maybe even got onto the motorway, the traffic and weather conditions were so bad that he turned back, he could even have phoned her to let her know he was coming back and that's why she picked up the pizza, once home he found out she'd texted this guy and he went ballistic.......... once it happened, he had to go to Sheffield as he needed an alibi.... left her body on the way (I am probably in the absolute minority, that I can see how her body could have been covered in snow and not been noticed) I think his brother said he arrived earlier than he did (his wife and child could have been in bed asleep) he could easily have said it took him @4-5 hours instead of 3 due to adverse weather/driving conditions)
Until I hear the police categorically say he has been eliminated as a suspect, all my money is on him.
