(FOX NEWS) Large donations are not uncommon when Salvation Army red kettles hit the streets all across the country -- but in the Twin Cities, the charity is stumped about who's behind an annual set of donations nearing the $100,000 overall mark.
Since 2011, a generous donor has been secretly dropping wads of $100 bills in increments of $1,000 or more inside the kettles all around the two cities, the Duluth News Tribune reported.
The mystery benefactor has a nickname: “St. Grand.” Since 2011 and including this season, St. Grand's donations reportedly have totaled $96,002.
“Last year, we had two bundles wrapped in $1 bills,” Salvation Army spokeswoman Julie Borgen said, explaining the extra two bucks. “We assume it’s the same donor since the method is always the same – a roll of crisp $100 bills bundled together and dropped in a kettle.”
