Conservation experts and federal agents say they're looking into the violent deaths of several bottlenose dolphins along the northern Gulf Coast this year, including one that was shot and another that was stabbed with a screwdriver.
Samia Ahmad, a spokeswoman for the Institute for Marine Mammal Studies in Gulfport, Mississippi, said at least six dolphins had died as a result of foul play since January. In one case, a dolphin had its jaw cut off, she said.
