Back in August 2012, Alan Holyoak went to Seaside, Oregon, for his niece's wedding. He never expected that he'd come back a hero.
Holyoak has a background in marine biology and teaches at Brigham Young University. Returning from an early walk one morning, he and his wife saw a person staring at an object lying just where the waves break on the beach.
"I couldn't tell what it was from a distance," Holyoak told The Dodo. "It was pretty big. I didn't know if it was a juvenile dolphin or what. So we walked over and it was about a 4-foot shark in the water. It was just being rolled around in the waves."
