In 2365, Larell and associates Hain, Krit, Nahsk, and Morn, planned and executed the Lissepian Mother's Day Heist, a notorious robbery that occurred on the planet Lissepia, in which one thousand bricks of gold-pressed latinum was stolen from the planet's Central Bank.
Though all thieves managed to escape the authorities on Lissepia, Morn double-crossed Larell and the others by extracting the latinum and storing it in his second-stomach, with the aim of keeping it for himself following expiration of the statute of limitations.
In 2374, Larell attempted to find the latinum stolen in the heist. She double-crossed the others by pretending to be Morn's ex-wife with the intention of finding and keeping the latinum for herself. However, she and the others were unsuccessful and later arrested on the space station Deep Space 9. (DS9: "Who Mourns for Morn?")
