Brian: 
>CCD where the hive would be basically MT with few if any live bees. 
 
exactly so -- about 1 cup only of corpses 
 
A normal deadout will have ~ 1 gallon corpses  
A varroa crash will have 1-2 liters 
 
No bees (bodys)  in frames 
95% of the feed still there 
No corpses on 'porch' 
No apparant pile in front of hive? 
 
When did they go?  My guess is Oct/November 
 
Peter: try reading more closely
