Washington police officers responded when a local Goodwill store reported a cooler someone had donated that was filled with marijuana.
She told InsideEdition.com the cooler contained 3.75 pounds of marijuana, with street value of approximately $24,000.
Willis explained that Goodwill employees believe the cooler was dropped off Monday night, but, "they’re not exactly sure how it was donated."
Officers are continuing to investigate surveillance footage in hopes of finding the cooler's former owner.
"There’s lots of people claiming, 'I think that’s my cooler’ [on social media],'" Willis joked. "But the possibility of us knowing really who did it is very small."
It is legal to carry up to one ounce of marijuana in Washington state. However, Willis explained the cooler contained nearly 60 ounces of the substance.
