.... bodies of dozens of dolphins and baby porpoises near Miami, Florida and across the pond along Scotland’s East Coast. These aquatic mammals where literally beaten to death with multiple internal injuries, lacerations, contusions and the like.
It's a Gang thing. Dolphins and Porpoises just don't like each other.
I've seen some of their fights, wasn't pretty. Switch-blade knives and Saturday Night Specials were everywhere. A few even had TEC-9s (the gang leaders). It was utter carnage.
Actually, dolphins have been known to attack and kill porpoises.
