Natascha Kampusch was 10 years old when her mother let her walk to school by herself for the first time.
That morning, in May 1998 in a street in Vienna, Austria, Natascha noticed a man standing by a delivery van up ahead.
As she walked passed, the man grabbed her by the waist, opened the door to the van and threw her inside.
"Everything happened in one fell swoop," Natascha later wrote in her book 3,096 Days.
"The moment the delivery van door closed behind me I was well aware of the fact that I had been kidnapped, and that I would probably die."
Once inside, the man, an IT specialist by the name of Wolfgang Priklopil, told Natascha to sit down on the floor and not move.
Remembering a crime show she watched on TV, the 10-year-old knew she needed to note as many details about her kidnapper as possible to later help police. So she asked him a question.
"What size shoes do you wear?" she said, before being snapped at her to be quiet.
Natascha later arrived at Wolfgang's home in the suburb or Strasshof, not far from her parent's home.
Once there, he carried her into a tiny five-by-five metre, soundproof, windowless cellar under the garage – a space she would call home for the next 3,096 days, or eight years.
Wolfgang told her the doors and windows were booby trapped and her family had forgotten about her.
