Almost every time the dolphin was not left alone and the attackers inflicted other injuries to the poor creatures.
With the help of scientists from the Institute for Marine Mammal Studies authorities have a better chance of understanding and catching the attackers. Unfortunately recovering and analyzing the cause of death for a dead dolphin is no easy thing.
Police suspects the killings were most likely done by a group on rampage. The people who did this are considered to have some serious mental problems as Police suspects the dolphins were killed to be mutilated afterwards. Once Police catches the people responsible for these acts it will apply big fines and jail sentences as the law is not kind on criminals.
