What also must be regarded as evidence against David Bain is the almost complete lack of evidence pointing to Robin Bain in the murders of his family members. Both prosecution and defence agreed it could only be either Robin Bain or David Bain, bearing this in mind there is only one evidence item that was presented by the defence that they said connects Robin to the murders, this one disputed item was the bloody sock prints http://davidbain.counterspin.co.nz/evidence/bloody-sock-prints-in-the-hallway-0 which were found leading away from the bloody murder scene of Stephen Bain, but as the evidence showed Robin Bain had blood free socks on when found by police, and the only other blood found on him proved to be his own, the defence said he changed his socks along with his other clothes putting the bloody ones in the washing basket which David admitted washing. David admitted to the police that a pair of socks and tracksuit pants and top found in the wash were his. Because there was just one item of highly disputed evidence against Robin the defence mainly concentrated on trying to show Robin committed suicide and defaming and besmirching his good reputation.
David said in statements to police that Robin was wearing the clothes (tracksuit) he had been wearing the previous night.Robin wore a little woollen beanie at night to keep his balding head warm. If you are to believe the Bain Defence scenario, he would have also had that on while fighting Stephen and yet somehow it remained on his head, blood-splatter free and wasn’t pulled off in the struggle or lost in the chaos. It was still on him when he was found.
