Witness Allison Keller told Hawaii News Now that the man appeared unconscious as rescuers pulled him from the water and performed CPR Saturday morning. "As we got closer, I saw some blood on his stomach and then I got looking a little bit more and his wrist, it looked like the skin on his wrist was just torn off," Keller said. "And then I got looking closer and his entire left leg from his knee down was just missing."
The victim was a 65-year-old resident of California, according to Hawaii's Division of Conservation and Resources Enforcement. Officials didn't immediately release his name or say where in California he was from.
The man was swimming about 60 yards (55 meters) from shore when the attack happened, according to authorities. The last fatal shark attack in Hawaii was in 2015, when a snorkeler off Maui was killed.
