Drone video captures killer whales trailing New Zealand swimmer

NEW ZEALAND -- Drone video captured three killer whales trailing a swimmer at Hahei Beach in New Zealand.

Swimmer Judie Johnson told local media she thought the killer whales were dolphins until she saw the color on their backs.

She says she was wearing a black wetsuit, and hoped the killer whales would not mistake her for a seal and attack.

They swam alongside her for a couple minutes, before swimming away.
