"My life has changed,'' he said.
When she got the call from him Monday, his wife said: "I had no words. ... My heart wanted to come out of my chest.''
"All I can say is I feel very happy that God has blessed us with this prize,'' said Sanchez, who is from Tlaxcala, Mexico.
Quezada is the father of five children, ranging in age from 23 to 5. He has one grandchild.
In the Dominican Republic, Eliana Quezada, the winner's 26-year-old niece, was thrilled by the news of her uncle's massive windfall.
"One of my aunts called me and told me that my Uncle Pedro won the lotto, then I saw him on TV,'' she said Tuesday in Jarabacoa. "I was happy, happy, so I ran into the street!''
The single mother of two children is one of the winner's few relatives still living in the Dominican Republic. Most migrated to the United States years ago, and she said she hadn't seen her uncle in about 10 years.
When asked whether she had any expectations now that her lucky uncle was an incredibly wealthy man, Quezada, a manicurist, said she would love for him to bankroll a trip for her to visit the U.S. to see her many relatives.
"I would like my uncle just to take me there to see my family, my grandparents and my uncles,'' she said.
The largest Powerball jackpot ever came in at $587.5 million in November. Nebraska still holds the record for the largest Powerball jackpot won on a single ticket -- $365 million -- by eight workers at a Lincoln meatpacking plant in February 2006.
Powerball is played in 42 states, Washington, D.C., and the U.S. Virgin Islands.
