Upon reexamining the Kurt Cobain death case, Seattle Police have found a roll of film. The roll was developed and two pictures were released. You can view the pictures at the below link.
Note how there is no water bottle or even a lid. Junkies often carry a water bottle around with them or else use a lid to hold water to use to shoot up.
