The winner of the largest prize in Louisiana Lottery history still has not come forward to claim it, a week after the jackpot drawing.

A Lottery spokesman on Friday confirmed that they have not yet heard from the $191.1 million winner.

The winning ticket was sold at Brownies Shop Rite convenience store in Eunice in St. Landry Parish. It matched five numbers -- 18-22-29-54-57 -- and the Powerball, 8.

It's the first time since 2013 that a Louisiana store has sold a winning Powerball jackpot ticket.

The winner has 180 days from the Oct. 25 drawing to claim his or her prize.
