"I was stunned. I couldn't believe it," Slatten said. "I can't express it. It was something else."
Slatten said he took the ticket with him to visit his fiancee at work to tell her the good news, and afterward he ran some errands including a stop at the O'Reilly's Auto Parts store in Sparta.
Slatten said he realized the ticket was missing about an hour after he left the store.
"I couldn't find it anywhere," he said.
The player said he retraced his steps from the day and he had his second lucky discovery of the day when he spotted the ticket in the O'Reilly's parking lot, right next to a parked vehicle's driver's side door.
"It's a million-dollar ticket, and someone stepped right over it," Slatten said.
Slatten said he and his fiancee are planning to buy a house and new vehicles with the winnings. He said the remainder will be invested and will allow the couple to live life with "not a whole lot of worries."
