The husband of Sa'u Justina Sa'u, the late chief executive of the Unit Trust of Samoa, has been arrested and charged with her murder.
Sa'u died unexpectedly last month and police had been waiting for a post mortem.
Police Commissioner Fuiavailili Egon Keil told Newsline Samoa the post mortem and investigation had revealed possible foul play.
Kolani Junior Lam will appear in court on 26 November.
