Other than that which I refer to, there were no reinforcements called upon because of the sheer size of the premises, other than a second group of firearm officers arriving at the incident at about 7am, or thereabouts...
Except, that a particular group of additional officers (SOCO 1st team, from Headquarters) were requested to attend whf in possession of cameras and recording devices. Yet, officially although this request is documented, there is an entry in police logs, that this request was cancelled...
However, it was not cancelled - since the request was a reference to headquarter SOCO to attend the incident, and which they did do!
It was Headquarter SOCO (DC's Oakey, and possibly, DC Henderson and DS Eastwood) that attended whf and who recorded the bodies insitu, and who took a crime scene video of the various locations and positions of victims bodies, and key exhibits!
