Lillyan Maxwell, 4, was reunited with her mother about 20 minutes after the car was stolen.
"No words can describe the love you have for your child. I never thought that something like this would happen," said Kristen Dowell, Lillyan's mother.
Dowell said she parked her black Chrysler by the Redbox at the Circle K around 11 p.m. Sunday. The gas station convenience store is located on the corner of Treaschwig Road and Cypresswood Drive.
Dowell said she got out of the car to pick out a DVD and left her daughter sleeping in the backseat, keys in the ignition.
"It was a split second, a split second. Literally, my back was turned three minutes. I turned around and she was gone," Dowell said. "I made a mistake."
Dowell says she stayed by the Redbox. But the clerk says Dowell came into the store.
"When she walked out, I heard her screaming. I thought something happened to her. She said her kid got stolen with the car," Circle K clerk Jessy Rodriguez said.

Rodriguez called 911.
Deputies spotted Dowell's car on the road and a chase began. At one point, speeds reached 120 miles per hour. The pursuit lasted for about 15-20 minutes.
Pct. 4 deputy constables found the vehicle abandoned in the 4500 block of Monteith Drive with the girl. She was unharmed.
"Luckily, my daughter was asleep for a lot of it. She told me she woke up and Mommy was not driving," Dowell said.
