I do know he came back on the 2nd of Sept and the investigation had changed and at some stage he had to go back to WHF because of this, 1) Was to take soil samples, whether he took more photo's? Also what I found interesting about Bird, he only took crime scene photos, exhibit photos were done by civilians at HQ.
Sorry, just found part of his statement, he has been asked a question in COLP statement, if he took a photo, he goes on to say "no I didn't, the only photography I took was at the scene, the photography at headquarters is done by civilians?
