Gabriela Cowperthwaite was a mother who took her kids to SeaWorld, she did not have any background on Orcas or in activism, but she became fascinated and horrified by Dawn Brancheau’s death in 2010. Brancheau was one of SeaWorld’s most experienced and top trainers at SeaWorld. After this horrific incident Cowperthwaite looked farther into her death and learned all she could about the whales. Her first thing she looked into was from an article called Killer in the Pool by Tim Zimmerman, and she learned that before Brancheau’s death there were two more deaths. This made her question the ethics about keeping Orca’s in captivity. She peeled back the layers and started to expose SeaWorld’s wrong doings.
