Cereza recently yanked some old lottery tickets out of a cookie jar at his house. One of them turned out to be an Illinois Lottery ticket worth $4.8 million, CNN affiliate WGN reported.
"When I realized we had all six numbers, it was that shocking moment of, 'whoa, can this really be?'" Cereza told the station.
"So I called my son over and asked him to double-check this, and he looks it through and goes, 'Yep, looks like a winner,'" Cereza said.
The family will use the winnings to pay off the mortgage on their home, which was facing foreclosure, according to WGN.
