Investigators from multiple agencies are searching for a missing woman, man and his 2-year-old girl who were all last seen in late May.

On Tuesday, Pullman police were working with the Moscow Police Department and the FBI to investigate a report of a missing 2-year-old girl named Seraya Aung Harmon. She was last seen with her father Aaron Aung on May 29.

According to police, the two were reportedly traveling to Montana for a fishing trip but never returned.
