Ron Spence was in the parking lot of the Mount Dora, Florida Walmart when a woman flew past him.
"The lady with the shopping cart full of stuff went running past me," Spence said.
Spence watched as three employees tried to chase down a suspected shoplifter who police said was shoving the stolen stuff into a red Mustang.
"There was food, laundry detergent, clothes, bedding products," said Robbin Fayne, from the Mount Dora Police Department.
"Two old ladies and a teller clerk against a car, doesn't look like good odds," Spence said.
Spence said he hopped in his minivan, and Employees scrambled to avoid being run over as he came to block the Mustang's escape.
"Once she backed up and saw I was in her way, she rammed right into the front of my van. Then, she backed up and rammed me again," said Spence.
Spence, however, said he wasn't going to back down.
"Hey, I'm not going to do any more damage at this point after I've been hit three times already, I might as well go ahead and finish this," Spence said.
The Mustang was thrown in reverse, narrowly avoiding a crash with one car and then another, police said.
Then, Spence said he pushed the car up on the curb, pinning it between the building and his van.
"She's sitting there burning her tires off. Smoke is going everywhere," Spence said.
Police said the driver, Pamela Wright, and her passenger, Alyssa Alicea, weren't going anywhere, because of Spence.
"We don't recommend it, but in this case, we're glad we were able to catch these subjects," said Fayne.
"I can fix the car. Those two are in jail," Spence said.
Spence said says he was happy to help, but now he's just worried whose insurance will cover the damages to his minivan.
