Joanna Barnes, who was in S4 "Didn't We Meet At A Murder" has passed away at age 87. Her other notable credits over the years included roles in "The Parent Trap", "Spartacus", "The War Wagon", a regular role on the 1965-66 series "The Trials Of O'Brien" starring Peter Falk, scores of guest shots on TV over the decades and even her own daytime talk show on ABC in the late 60s.

The one interesting quirk about her guest shot on Five-O is that for the tag scene when her character is arrested it's filmed entirely in a long shot with voiceovers, indicating she wasn't available for that scene and they had to use a double.
