North Shore residents have raised a $1,200 reward for information leading to the arrest and conviction of the person or people responsible for the slaughter of a protected green sea turtle last week.

A 200-pound, 30-year-old female turtle called Honey Girl was discovered buried in the sand on Laniakea Beach on Saturday. Her breast shell had been removed and a flipper was missing.

An examination of her remains indicates that the animal was healthy, died quickly and had knife marks where muscle was "picked clean" from her body, according to the results of a necropsy provided today by the National Oceanic and Atmospheric Administration Marine Fisheries Service.

The cause of death was uncertain.

The necropsy concluded that the turtle was killed and her muscle and organs were taken.

Several North Shore residents pledged the reward money at the North Shore Neighborhood Board meeting Tuesday in hopes of bringing the criminal or criminals to justice, said board member Warren Scoville.

"I in front of God and 'Olelo TV pledged a $500 reward and was quickly matched by somebody in the audience," Scoville said. That turned out to be David Druz, and later Marlu West called to offer $200 more, Scoville said.
