Strange, here's a Gibson at Anna's bedside the day Danny died and a Gibson by Anna's side the day she died.
I can see Thompson's motive to publish it in regards to the Horizons...but that wouldn't be necessary. I think it was a warning to the whole Gibson family and given to the press by Howard. When did he get back to the Horizons after the robbery?
Another thing...I remember the little tour after the robbery...Howard sat on the bed and opened an album and on the right hand page, there was what I'm almost certain...the pictures of Gibson in bed with Anna.
