Walla Walla officials only released a short terse statement, but they and the FBI raided a home in town and in College Place.  College Place police involved as well.

Here is the statement released by officials on Friday morning.

"Walla Walla Police Detectives assisted an FBI Agent today with the service of a Search Warrant in the 300 Blk of Chase Street. The investigation led to the application for Search Warrant and search of another residence in the 000 Blk of NE Rose St in College Place. Items of evidence were seized from both residences and the investigation continues. No arrests have been made at this time. Crimes being investigated are possession and distribution of Child exploitive materials. No further information will be released at this time"

We won't speculate, but in the past, almost always this ends up being tied to some sort of child pornography. We will update when more information becomes available.
