A father was killed and his nine-year-old daughter seriously injured while walking along a beach in the US state of Florida when a small plane crash-landed and hit them, authorities said. Wendy Rose of the Sarasota county Sheriff's Office said the pilot and his passenger were not hurt on Sunday when the Piper aircraft lost power and touched down next to the water's edge. "A man and one of his children who were walking on the beach were apparently injured by the plane," Rose said. She said the 36-year-old man was later pronounced dead. She said a local airport received a distress call that the plane could not make it back to the airport. "He knew he couldn't make it back to the airport and was going to try to land on the beach. And he did land at the edge of the water on the beach," Rose added. She said the girl was airlifted to a hospital, where she was apparently in critical condition. Kathleen Bergen, a spokeswoman for the Federal Aviation Administration, said the agency was investigating. She said the plane reportedly lost power but she had no other details. Rose later released a statement identifying the dead man as 36-year-old Ommy Irizarry and the injured girl as Oceana Irizarry, nine. Karl Kokomoor, 57, was the pilot and his passenger was David Theen, 60.
