Bundles of cash, stashed in the back of an armoire.
The worker notified his bosses - and the owners of ET Estate Sales and Liquidation of Washington state traced the furniture to an estate sale.
Eventually, the family of the owner got the $20,000 back.
The money belongs to a 78-year-old widow whose husband died in February and now lives in an assisted-living home.
The woman's husband put the money in the armoire years ago because he didn't trust the banks.
