Mr and Mrs Falkholt died at the scene,as did Craig Anthony Whitall,51,who was behind the wheel of the other car.
Passers-by dragged the two sisters to safety before both cars went up in flames.
Annabelle was flown to hospital,but died three days after the crash. She and her parents were farewelled at a funeral on January 10,where mourners remembered Lars and Vivian as"inseparable"and Annabelle as a kind and radiant person who loved life.
"Their lives ending on a highway makes absolutely no sense,"Vivian's brother Paul Ponticello said.
