A passing driver and his girlfriend saw the car upside down in the river and rushed to the family’s help. They managed to pull every member of the family out of the van.
Richard and one of his children were treated for minor injuries. One of the Good Samaritans was also treated for minor injuries including hypothermia.
Police say road conditions at the time of the collision were slushy due to an overnight snowfall.
Investigators say the minivan may have been attempting a pass and lost control on the slushy center area of the roadway.
