CrimeStoppers and the Honolulu Police Department are asking for the public’s assistance for information regarding a cold case homicide.

On September 28, 2010, at approximately 11:00 a.m., unidentified human remains were discovered by a construction crew in the Manoa area. It was determined that the skull sustained a gunshot wound and that the remains were placed there under suspicious circumstances.

A composite using the genetic markers of the skull was created by an HPD graphic artist, but it did not result in any additional leads. Remains were also sent to the FBI Laboratory in Quantico for DNA testing, and in 2023 a DNA profile was developed and the remains were tentatively identified. Further investigation revealed that the unidentified victim’s son resided in Washington State.

After a DNA reference sample was obtained and compared with the profile developed from the remains, the victim was confirmed to be William Hans Holling Jr. Holling resided in the state of Washington and had gone through a contentious divorce. He was last seen by his family and friends in January 1985 was known to travel frequently to Australia via Honolulu.

Anyone with information about this incident is asked to call CrimeStoppers at (808) 955-8300. The public may now send anonymous web tips to www.honolulucrimestoppers.org or via the P3 Tips App.
