The remains were stolen in a recent burglary of the owner's home in unincorporated Lynnwood.
The owner called the Lynnwood Police Department after seeing the photo of the box on recent newscasts, police said.
He was able to prove the ashes were the remains of his son who had passed away several years ago, police spokeswoman Shannon Sessions said.
The owner asked that nature of the boy's death and any other details about the child not be shared with the media.
The box and its contents were discovered by a guest staying at a Lynnwood hotel in the 4100 block of 196th St. SW. The guest found the box between two vending machines. The box was given to a hotel employee who called 911.
The box not only included the ashes but also a photo of a pre-school age boy that had a name and year written on the back.
