In case you haven't come across the following book, a C. J. Lindberg from Ba is mentioned a couple of times.
The majesty of colour : a life of Sir John Bates Thurston. Vol 1.: I, the very bayonet by Deryck Scarr.
You can see a preview of it on Google Books: http://books.google.com.au/books?ei=NWBdT948huOYBabflMkP&...
As you can see from the preview, he was involved with a murder in about Augst 1872. Check the Fiji Times from around that period.
I managed to find an article in the Fiji Times about the murder of one of my ancestors, Achilles Underwood in 1871. So I'm sure they'll be an account of this incident in 1872.
