The slain American prosecutor who was shot dead on a tiny Pacific island spoke to her dad the night before she died about her plans to move back stateside, according to report.

Rachelle Bergeron, who served as acting attorney general on the remote island of Yap, was fatally shot in the chest and leg Monday night upon returning home with her dog, officials said.

The married 33-year-old worked as a human rights lawyer in Manhattan before moving to the island destination in 2015.

Her father, Thomas Bergeron, said he was in disbelief and had spoken to his daughter the evening before she was gunned down, the Milwaukee Journal Sentinel reported.

In their final conversation, Rachelle talked about leaving her job and moving with her husband, Simon Hammerling, to Cheyenne, Wyoming.

“We had been on the phone with her the night before,” Thomas told the newspaper. “We talked about when she was going to move and where she was going to move to. That was the last we talked to her.”

He said his daughter was “very courageous” and “loved to defend those who were mistreated.”

“It’s been a very, very difficult time to lose someone like her,” Thomas said.

No motive has been identified in the fatal shooting, but the FBI has launched an investigation on the island.

Yap is situated about 4,500 miles west of Hawaii in the Pacific Ocean and is part of the Federated States of Micronesia.
