Washington woman, Idaho fiancé may have fled to Mexico with missing 2-year-old Seraya Aung Harmon: police

A recent Washington State University graduate and her Idaho fiancé may have fled to Mexico with missing 2-year-old Seraya Aung Harmon, according to the Pullman Police Department.

Seraya was last seen with her 21-year-old father, Aaron Aung of Moscow, Idaho, on May 29. That same day, Aung’s fiancée, 21-year-old Nadia Erika Cole, was last seen at the Seattle International Airport preparing to leave for a family vacation in Italy, according to police and a statement from Cole’s family.

“Initially, Aung was thought to have traveled to Montana because he was seen buying camping gear and a Montana map book in Moscow,” police said. “However, the investigation later revealed that Aung and Cole likely traveled to Mexico in a black 2014 Cadillac XTS with Idaho license 1L5147U.”

Authorities on June 5 issued an arrest warrant for Aung for first-degree custodial interference for allegedly violating a court-ordered parenting plan. Seraya was scheduled to be returned to her mother on June 3, police said.

Cole is not Seraya’s mother, her family’s private investigator previously clarified.

Cole’s Instagram shows her engagement to Aung in November 2023. Cole’s family issued a statement after her disappearance.
