The body of an unconscious diver washed up on an Australian riverbank near 110 pounds of suspected cocaine worth $14 million on Monday morning, police in New South Wales said Tuesday.
Emergency personnel performed lifesaving measures on the diver, but the man died at the scene.
Several packages containing a white powder that authorities believe is cocaine were located "in the immediate vicinity" of the diver.
The diver and the drugs washed up on the bank of Hunter River in Newcastle, a coastal city about 100 miles north of Sydney.
