One woman got lucky.
According to Colorado Springs police, the woman pulled up at the Walgreen's at 920 N. Circle Dr. about 7 a.m. Tuesday and left her car running with her two children inside the vehicle.
When she returned 10 minutes later, a man apparently intent on stealing the car had gotten in and started to drive off.
Police officers said they believe the man planned to steal the car until he realized there was a 3-year-old and an 8-month-old inside, parked it and ran away.
"This situation could have resulted in tragic consequences," Colorado Springs police said in a statement.
The woman, Takai Beard, 27, was served a summons for unattended motor vehicle and child neglect. She was booked into jail on an unrelated warrant, police said.
On Facebook, Beard said she ran into the store "real quick" to get her daughter milk before she dropped her kids off at daycare.
"I just want to thank God for protecting my babies throughout this foolishness," she wrote.
The number of motor vehicle thefts in Colorado Springs is on the rise, police said. In part, it's because of the wintry weather, and drivers leaving their cars running unattended.
"More and more parties are leaving cars warming up at home in the morning or while they run in a convenience store to buy an item or while dropping kids off at day care," police said.
It's not only unsafe, it's against city and state law, officials said.
