If all Jo Yeates footwear has been accounted for then Jo was not seen in the company of two individuals by the Landlord...Jo would hardly walk out into the snow in stocking feet. The murder therefore takes us back inside the flat...the pizza packaging may well be stuffed inside the sock. The boyfriend what was he doing for four hours before contacting the police ? he claims to have phoned Jo's parents when he arrived home to say she was not there..why not also phone Jo her mobile was in the flat and he would have heard the ring...surely raising his concerns...this is truly bizarre and I wonder why the pizza is so important...dna found on the packaging by of a person who claims to have been somewhere else can only be the reason.
