Some people are super generous.

Employees at a Goodwill in Monroe, Washington, were surprised to find 3.75 pounds of weed inside a cooler that was recently donated.

According to cops, the weed has a street value of $24,000, though looking at the photos the police tweeted, the weed looks super old, so that number is probably inflated.

Though cannabis is legal to possess in the state of Washington, it's illegal to have more than one ounce for personal use. So cops are currently examining surveillance footage to see if they can figure out who the kind person was that donated the pot.

They probably won't be able to write this donation off on their taxes.
