Carrollton police were called to a home on Tall Knight Lane just before 8 a.m. by a man claiming he had been stabbed by his wife.
He was taken to the hospital, where he is expected to survive.
Inside the vehicle, police found a woman, later confirmed to be the wife of the stabbed man, and three children, ages 8, 9 and 12.
One child was resuscitated at the scene by a Lewisville police officer, another was revived on the way to the hospital by Lewisville paramedics.
People who saw the rescue say they are thankful the children survived.
Deep tire tracks are still visible, showing the vehicles path into the pond.
