A single mom just won the largest lottery prize in her home state and announced she will be sharing the fortune with those who need it most.

Last month, 51-year-old Lerynne West was celebrating the purchase of her first home. After she moved into the house in Nedfield, Iowa, she and her sister stopped at a convenience store for pizza and coffee. While she was there, she picked up a Powerball ticket.

“I got my lottery tickets and we went back out to her trunk,” West told Cnbc. “I kind of just set those down at the foot in my purse — or so I thought — and didn’t think of them again until Sunday morning.”

West played lotto regularly but the most she has ever received was $150. After she checked her Powerball ticket numbers, she realized she won the $343.9 million jackpot — the largest lottery prize ever won in Iowa.

West chose to use the money to make an impact. She set up the Callum foundation, a charitable organization which will offer grants to initiatives that will alleviate poverty and hunger and improve education, animal welfare and veteran affairs.

She grew up in a working class family in Earlham, Iowa a small town of 1,450. Her father was a Vietnam veteran and a welder and her mother was a stay-at-home mom.

When she was 14, she worked on farms to “earn money to buy school clothes and help with the family. At 17, I left high school. At 19, I earned my GED. Soon after that, I started my family. I have three awesome, beautiful daughters.”

Aside from the Callum Foundation, which was named after her late premature grandson, she will give money to friends and family and set aside money for her grandchildren’s college tuition.

“I realize this is a life-changing moment,” West said as she claimed her prize at the Iowa lottery headquarters. “I’m excited to share my winnings with family and friends… I also plan to give to the causes and organizations important to my family through our newly-established Callum Foundation.”

“I want you to know that as I stand here today and I know the responsibility that I have to do good with this money,” she said, fighting back tears. “My life changed forever.”
