"NCIS: Hawai'i" returned to CBS on February 12, 2024, with the Season 3 premiere, "Run and Gun." The episode’s title card read, "In Loving Memory of William 'Kono' Dahlin."

Reports indicate he worked as a crew member and background extra on the procedural. Dahlin died of fatal gunshot wounds on July 19, 2023, following an argument at a bar.

Shortly upon arriving at a hospital, Dahlin was pronounced dead, with police ultimately charging the assailant with second-degree murder in addition to other charges.

Dahlin's online obituary states that he was 49 and is survived by three children — Karli, Tyler, and Jacob — as well as his father, sister, and brother.

The webpage shows that Dahlin was well-loved, both on set and within his community, as it includes tributes from people who have uploaded photos of him in addition to well wishes.

A video uploaded to Instagram by Hawaii News Report discusses Dahlin's death, and the post includes a comment from Noah Mills, who plays Jesse Boone on the CBS procedural.

Mills worked with Dahlin for almost two years, and wrote how the crew member, "Always put a smile on my face as he [did] for many others and will be dearly missed [...]."
