In the Hawaii Five-0 episode “Ke iho mai nei ko luna” (“Those Above Are Descending”), Adam (Ian Anthony Dale), Junior (Beulah Koale) and Tani (Meaghan Rath) put on their scuba suits and travel to the bottom of the Pacific Ocean. A murder has taken place in a remote underwater lab, and the killer, Claude Nostromo, is still on board. This storyline is inspired by real-life Danish inventor Peter Madsen who murdered and dismembered, among other things, Swedish reporter Kim Wall on his self-made submarine in August 2017.
Claude Nostromo is portrayed by Reed Diamond. He’s known for his roles on The Purge (Albert Stanton), Designated Survivor (John Forstell), Agents of SHIELD (Daniel Whitehall), Franklin & Bash (Damien Karp), Bones (FBI Special Agent Hayes Flynn), Judging Amy (Stuart Collins), Homicide: Life on the Street (Mike Kellerman), and in a variety of films including Moneyball (Mark Shapiro, SEE LINK ABOVE), Good Night, and Good Luck (John Aaron) and Spider-Man 2 (Algernon), among others. Hawaii Five-0 airs Fridays at 9 pm on CBS, right after MacGyver and right before Blue Bloods.
