Long Lost Family: Born Without Trace (2019) : 7x3

Sarah was left in the stairwell of a Surrey car park in 2001. She is the youngest foundling to appear on the show. Also looking for answers is Chris who, at three months old, was dropped off at a childminder's near Kings Cross in London, 62 years ago. He still needs to know who his birth family is and why nobody ever returned to pick him up.
