Despicable dolphin attackers at large in Gulf Coast 18 Nov 2012 A full scale hunt is on for those responsible for mutilating and killing dolphins along the northern Gulf Coast. A string of attacks spanning several months have occurred near Louisiana, Mississippi and Alabama. The dolphins have been stabbed, mutilated (one was found with its jaw missing, another with its tail cut off) and even shot with a 9 mm firearm. Killing dolphins is a federal offense and this spate of attacks has prompted an alert from the National Oceanic and Atmospheric Administration to area environmental and law enforcement agencies. Dolphins in the area are still recovering from the stress and death of the BP oil spill.
