The hectic 24-hour race to rescue a missing toddler began when her mother didn't pick up her older siblings from school earlier this week.
A search of the mother's home found she had been badly beaten, and her four-year-old daughter, Heidi Todd, was nowhere to be found.
It's still unclear just what happened to Heidi's mother, but a manhunt for the little girl began right away.
Police say an Amber Alert wasn't issued for the little girl because there wasn't enough information to create one, but Heidi's neighbors searched their neighborhood with flashlights.
In the end, Heidi wouldn't be found close to her home in Charleston, South Carolina.
She was discovered alive and well less than a day later in Riverside, Alabama, thanks to some quick thinking by a passerby.
A trio of railroad workers in Riverside were on the job when they noticed a car parked too close to the train tracks.
They discovered the blue sedan with Illinois license plates had a sleeping man behind the driver's seat, and an awake little girl in the passenger's seat.
Worried about the girl's safety, one of the workers, a 30-year-old father named Mark Burke, called the local fire department.
Burke later explained that as a dad himself, he couldn't just ignore the little girl in danger. As he soon found out, Burke made the right decision.
