Monday marked four years since Kauai resident Amber Jackson was killed and there still have been no arrests in the cold case.
In July 2010, Jackson's body was found in a remote wooded area in Kealia. An autopsy showed she had been assaulted.
The 57-year-old Hawaii State Teacher's Association employee had been reported missing.
Anyone who may have information on this case is asked to call Kauai police.
