Robin had some minor injuries on this hands that, belatedly, Joe Karam has tried to argue were inflicted as a result of his alleged activities on the morning of the murders. It is well known that the day prior, Robin was refitting guttering on the house which offers a valid explanation for the injuries. See photos.
Blood??? That the hand is obviously palm up meams the blood would drain to the back of the hand but the colouring appears too brown for that and too brown for relatively fresh blood, the other marks claimed to be tooth marks reies on a long discredited forensic belief surrounding tooth marks, The only tooth mark recognition now accepted as having a basis in truth is bites to soft tissue and where there is an easily recogniseable irregularity in the shape of the teeth. For a forensic orthodontist to posulate marks are from a tooth or teeth when inflicting a punch to the teeth would be quite simply rubbish not even reaching the strength of junk science. It is simply amazing that a orthodontist was willing to place his name on such evidence which would make him a laughing stock in his profession.
The colouring is much more likely th be simply shadow from the very poor lighting in the old morgue in Dunedin which was only taken out of service about 2001 when the new morgue was completed in the basement of the Dunedin Hospital of the Cumberland Street Clinical Services Block. The old morgue is a small brick building on Princes Street in the Southern Cemetry North East Boundary
