HONOLULU (HawaiiNewsNow) - It's been four years since Amber Jackson was murdered on the Garden Isle.
The 57-year old Kapa'a woman went missing on June 23, 2010, her body was found days later by pig hunters in Kealia.
Kauai Police know she was murdered, but there have been no arrests. The wait for answers has been agonizing for loved ones.
"More and more depressing," says Jackson's former boss at the Kauai HSTA, Tom Perry. "Whoever did it, is getting away with it."
The Kauai Police Department has had an outside review of the murder case and could soon be sending out evidence.
"It would be testing for DNA," says Assistant Chief Roy Asher, "We utilize private labs, as well as the Honolulu Police Department and the FBI."
Jackson, a former HSTA Secretary from Kapa'a was last seen by co-workers.
Despite a hefty reward -- $20,000 -- and a new cold case squad, Kauai Police say the case went cold.
Assistance Chief Asher says recent advancements in DNA testing could help.
"Refined their techniques," says Asher, "(They can) find evidence or DNA where previous tests couldn't."
Jackson's nephew, Matt Alexander says he is cautiously optimistic, "(We) watch TV and see how fast ... They don't happen that fast in real life."
