Missing Pullman couple, two-year-old child possibly in Mexico, police say

A young couple and two-year-old girl who recently went missing from Pullman are now likely in Mexico, police say.

Authorities believe 21-year-old Aaron Aung may be on the run with his fiancée, 21-year-old Washington State University grad Nadia Cole from Seattle, who has not been seen since May 29. Aung's two-year-old daughter is also believed to be with them.

Pullman Police posted an update to the missing persons case on Friday, which says Aung and Cole may have traveled to Mexico in a black 2014 Cadillac XTS with Idaho license 1L5147U.

Investigators initially said Aung took his daughter and fiancée on a fishing trip to Montana. However, police say the cars associated with the two of them were left in Pullman.

The mother of the missing two-year-old girl spoke out after an arrest warrant was issued for Aung.

KHQ in Spokane spoke to the girl's mother on Wednesday.

"When I found out she was missing, it was the worst day of my life. Every day since has been the worst day of my life," said Samara Harmon, the two-year-old girl’s mother.

The two-year-old girl’s mother is even more concerned because her daughter was dealing with severe constipation that sent her to the emergency room.

"We were advised by the doctor, we being Seraya and I, that if she didn't pass this soon, should could become septic, which is fatal," Harmon said. 

Aaron Aung is described as being 5’9, weighing 135 pounds, with black hair and brown eyes. He's wanted for first-degree custodial interference.

The FBI and Moscow Police Department are now helping Pullman Police with the search.
