A 7-year-old girl drowned and her mother suffered serious injuries after the car she was driving ended up submerged in a Missouri pond on Saturday, investigators said.

30-year-old Reem Alkhirafi was driving in Warren County, about an hour from St. Louis County, when dust in the road “obstructed” her vision, according to Missouri State Highway Patrol. The dust had been kicked up by the vehicle in front of hers, Fox 2 reported, citing the Metro West Fire Protection District.

In the crash report obtained by Fox News, investigators said Alkhirafi then drove off the road and landed in a pond. Her three children were inside the car at the time as well.

She reportedly didn't see a curve in the road before driving into the private pond.

Alkhirafi got out of the car and, along with bystanders, was trying to save her children before first responders arrived, the television station reported.
