WELLINGTON, New Zealand (AP) — Hundreds of people are expected to attend a memorial service on Tuesday for American prosecutor Rachelle Bergeron, who was shot and killed last week in the Pacific nation of Micronesia after returning home from a run with her dog.

No arrests have been made in the case, which friends believe was related to her work as acting attorney general of Yap State. Her duties included being part of a human-trafficking task force.

Yap officials say they've completed the initial phase of their investigation and have identified several persons of interest.

Constantine Yowbalaw, the director of youth and civic affairs for Yap State, said flags were being flown at half-mast on Yap island and the state legislature had passed a resolution to remember Bergeron.
