Two men are alleged to have conspired for a month to kill a Micronesian attorney general, before she was shot dead two weeks ago.
The revelation comes as the pair charged in connection with the murder of Rachelle Bergeron in Yap state are named for the first time.
Criminal charge sheets allege Anthony Teteeth killed Yap's acting attorney general after firing at her three times with a shotgun.
The charge sheets, shared with RNZ Pacific by online news outlet The Kaselehlie Press, show Mr Teteeth faces six charges, including murder.
Co-defendant Frances Buchun faces five charges, including conspiracy to commit murder and possession of illegal firearms and ammunition.
The charge sheets allege Mr Buchun drove Mr Teteeth to Ms Bergeron's home on the night of her murder on 14 October.
The defendants are alleged to have plotted the murder at least a month in advance.
They were denied bail in the Yap Supreme Court on Friday and will appear again on 18 December.
