Robbery of Bamonte's
At an apartment, Dickey was counting the money they made when Oswald arrived. Oswald gave them delicious cannolis, and they ate them quickly. It was later revealed that the cannolis were poisoned, and Dickey and the two robbers died, while Cobblepot sauntered out with all the money.
