Investigators said the 33-year-old St. Louis woman and her daughters, ages 13 and 8, were on the second floor of the home when they felt the house begin to shake and looked out of a back window to see a bulldozer rolling toward the home, the St. Louis Post-Dispatch reported Thursday.
"She saw the driver of the bulldozer leap from it, leaving it in gear," St. Louis Police Lt. Robert Ceriotti said. "She grabbed her two kids and ran out the front.
"When I tell you it's a bulldozer ... this is a massive, massive piece of earth-moving equipment," Ceriotti said. "It's almost as wide as the house. I can't believe this lady is so fortunate to be alive. It's God's work is what it is."
The woman and her daughters, who were not injured, have moved in with a relative. Police said they had to leave all of their belongings behind because the house is too dangerous to enter.
Police said they are trying to identify the driver of the bulldozer, who had disguised his face with a surgical mask.
"We do have a person of interest," Ceriotti said. "She's going through some civil actions with a relative of her deceased fiance, but we don't know if it's him."
