Tonya Henry suggested that all DAs should have each of their leagues go to WA Unclaimed Property and search for their league name. There appears to be a lot of Washington State Little Leagues that are owed money by the state.

I went in and found several leagues in my district that are owed money. You might also check just “Little League” in addition to leagues by name. I found a couple of those entries with the address of one of the former presidents of a league in my district.
