To me that looks like the belt has slipped what with the cam being snapped and all, it looks as though the valves have been slammed home by the piston pushing them up into the cam and snapping it clean in half while at the same time snapping one of the rods,

You said it had no oil pressure which is also possible that it could be the oil pump chain having snapped of the pump its self having shit its self as they are directly behind that hole too!
