No coolant??? Can you see if there is any oil contamination in what's left (try the expansion tank/bottom radiator hose)?

Is the engine oil white and creamy?

Had a look at the plugs? Black would indicate cyl-oil chamber leak, white generally is a cyl-coolant leak, and grey-grey plugs would be a leak from cyl-cyl without breaching any fluid lines. Absence of coolant would indicate a head gasket most likely.
