Anthony Teteeth and Frances Buchun are charged in connection with the murder of Yap State's former acting Attorney-General, Rachelle Bergeron.
The US citizen was shot outside her home in October 2019 in a rare act of violence for the small island state.
The Yap State and FSM National court cases concerning the killing have been delayed, hampered by a travel ban announced in January because of the Covid-19 pandemic.
