He was a Guatemalan immigrant who spoke little English and had a fondness for scratch-off lottery tickets; they were two clerks at a Long Island gas station who saw an opportunity.

When the clerks scanned Marvin Choy Nij’s Take 5 lottery ticket and gave him $774, congratulating him on his windfall, he never suspected the real worth of his lucky ticket: $74,892, which the clerks, Yalcin Nergiz, 41, and Yunis Ozturk, 33, promptly cashed in for themselves, the Suffolk County district attorney, Thomas J. Spota, said this week.

With Mr. Ozturk’s brother, Orhan Ozturk, 47, the district attorney said, they split the profits, which came to $48,318.27 after taxes. They were due to be arraigned on Wednesday on conspiracy and grand larceny charges, but the arraignment was postponed until next Tuesday to wait for a Turkish interpreter.

The handful of Bingo and Take 5 scratch-off tickets that Mr. Nij, 28, brought into the Valero station on Peconic Avenue in Riverhead, in mid-March, did not seem like much — until his last ticket was scanned.
