(Horn Island) - Authorities say a dolphin's head has washed up on Horn Island and another dead dolphin was found in Gulfport, Mississippi.
The director of the Institute of Marine Mammal studies in Gulfport says experts will examine both Monday.
He says both dolphins were adults, and had been dead a few days.
He could not say whether the deaths are related to the dolphins found shot, stabbed and mutilated last month.
A $5,000 reward is being offered for information about anyone involved in those incidents.
