An apparent gold mine found in the convenience store trash was too good to be true.
Police said Michael John Dornbrock, 45, of 2306 W. Fourth St., Cedar Falls, found a batch of winning scratch-off lottery tickets in the garbage of a Jefferson Street store.
The tickets -- 16 in all -- had already been redeemed for cash and then thrown out, according to the police report.
But Dornbrock dug them out and took them to the Hy-Vee grocery store on University Avenue where he tried to turn them in for cash Jan. 2.
Iowa Lottery Commission officials determined the tickets had been previously redeemed, and Waterloo police arrested Dornbrock for lottery fraud Tuesday.
