The Texas Lottery says the winner claimed a second-tier Mega Millions prize worth $1 million for the drawing on June 8.
The resident, who has chosen to remain anonymous, didn't buy the ticket in Houston, however. The lucky ticket was purchased at the H-E-B on 12407 Mopac Expressway in Austin.
The Quick Pick ticket matched all five of the white ball numbers drawn (14-30-33-44-56), just not the Mega Ball number (13).
In May, a Houston resident scored a $30.25 million jackpot prize.
