Two of five children who were trapped in a car submerged in an icy suburban Minneapolis pond have died.
Five-year-old Zenavia Rennie Adied and seven-year-old Alarious Coleman-Guerrido died on Thursday night.
The driver, the mother of three of the children, made it out of the car unharmed after it sank in the St Louis Park pond.
Family lawyer Rick Petry says the other children remain in hospital in critical condition. The mother, Marion Guerrido, was not taken to hospital.
The first child was pulled from the water about 25 minutes after the car veered off a highway ramp and into the pond. The last child who was removed had been in the water for 45 minutes.
Passers-by tried to rescue the children before police arrived, but the 1998 Pontiac Grand Am was submerged in about 9ft of cold water. State patrol officer Lt Eric Roeske said the "incredibly cold, nearly freezing-temperature water" would have made it difficult for anyone to reach the children and came up to the neck of one would-be rescuer who stood on the roof of the car.
Police said there was no indication that Ms Guerrido intentionally drove into the water and experts are investigating the cause of the crash.
