"We do have some claims to investigate," he said in an email shortly before the 5.p.m deadline. "So we can say as of right now, no one has come forward with the winning ticket. But we have had lots of inquiries and the potential for more claims."
If none of the claims pan out, it will be the largest unclaimed prize in California Lottery history and the money will go to the state's schools.
Lottery officials had sent out repeated calls for the winner to contact them, and media coverage ramped up as the deadline dwindled to days and then hours.
"If by some miracle you happen to find this extremely valuable piece of paper, the California Lottery urges you to sign your ticket in ink and get it to one of our lottery district offices," a Wednesday statement said.
The SuperLotto Plus ticket was sold on Aug. 8 at a 7-Eleven store in Los Angeles. The winning numbers were: 46-1-33-30-16 and the Mega number: 24.
A California winner also has not come forward to share in the Jan. 13 multistate Powerball prize of $1.6 billion. Two other winning tickets were sold in Florida and Tennessee, but only the Tennessee winners have claimed their cash so far.
