“I looked and couldn’t see anything but I walked over and I could see a silver car in the water,” said Moriarty, who said upon closer inspection he saw the two elderly people in the car.

“I took out my phone and wallet and jumped in,” Moriarty said.

When he wasn’t able to open the driver’s door, quick-thinking Moriarty went for the back door which allowed the water in and the nose of the car to reposition itself.

“It equalized the pressure and I was able to open the drivers’ door,” he said.

The Independent reports that the two American tourists were part of a group visiting the area and were transported back to Killarney with others in their group.
