( CNN ) -- The holder of one of three winning tickets in last week 's record $ 656 million Mega Millions drawing came forward Friday to claim a share , Kansas Lottery officials announced . The winner -- a single ticket holder -- has chosen to remain anonymous , state lottery director Dennis Wilson said . `` The person looks forward to retirement , '' Wilson said . Kansas was one of three states where three tickets matched the winning numbers -- 2 , 4 , 23 , 38 and 46 , with a Mega Ball of 23 -- amounting to an equal share of roughly $ 218.6 million , before taxes , under the annuity option . The Kansas winner , who bought the winning ticket at a Casey 's convenience store in Ottawa , chose the cash option to collect the winnings -- $ 157 million . `` They were still just in awe that they had won it , '' Wilson said of the winner , who did n't know the ticket was a winner until Monday . The other winning tickets were purchased in Maryland and Illinois . The Kansas winner is the first to officially come forward , just a week after the winning numbers were picked . Meanwhile , Maryland lottery officials have been responding to a flurry of questions from the media this week after a Baltimore-area woman told the New York Post that she had one of the winning tickets . However , in a bizarre twist of the story , Mirlande Wilson , a 37-year-old single mother of seven who works at McDonald 's , told the Post on Friday that she is n't sure where she last had the ticket . `` I 'm still looking for it . I have n't even looked in my uniform pants yet , '' the Post quoted Wilson as saying . `` I 'm still looking everywhere to find it , in my purse , everywhere . '' The state 's lottery director said Thursday he has n't seen the ticket , but he also says no one else has come forward saying he has it . Carole Everett , a spokeswoman for the Maryland Lottery , said Tuesday she does n't `` put much stock in that story . '' `` She claims she won , '' Everett said . `` She ca n't produce a ticket . ... In our opinion , until they walk in that door , hold that ticket , produce valid identification and our security people can process and validate it , it does n't matter . '' If Wilson is determined to be a winner , a showdown could be brewing with her McDonald 's co-workers . They are demanding a share because they say they pooled their money to buy several tickets . Wilson has said the ticket she bought was separate from that . CNN 's Tom Laabs and Brian Todd contributed to this report .
