Carlos Pizarro's sudden disappearance from Strömsund in Jämtland 18 years ago has been a mystery.
It has been described that 22-year-old Carlos, who had a developmental disorder, had no known enemies.
- He felt safe in Strömsund.
He was liked by everyone, says Carlos' mother, Estrella Pizarro in the documentary.
But in the third part of the documentary series, several teachers and former students now appear and give a completely new picture.
- He was very exposed, it only got worse and worse, says the former student Caroline Sjöberg.
Convicted of violent crime
The document from the inside editorial staff has interviewed about 90 young people who then went to high school and high school.
They describe how the bullying and harassment worsened drastically in the last weeks before the disappearance.
A group of young men in their 18s are singled out for having exposed Carlos Pizarro the worst.
Most of the group were already convicted of violent crimes and some were openly Nazi.
- Partly he was an immigrant, partly he was mentally handicapped.
He had no value for them, says Charlotte Westlin, who then worked as a high school teacher.
One of the former high school students, tells in the documentary:
- I was one of those who bullied.
There's nothing I'm proud of today.
Denies bullying
After Carlos' disappearance, several of the designated students have committed more serious violent crimes.
- There was an absolute reason to check them out extra-extra.
Even before they committed the more serious crimes, such as murder and other things, says Lili-Marie Wassdahl who was Carlos' contact person.
Most of the most designated people, with whom SVT has been in contact, today deny that they have bullied Carlos or have spread Nazi and racist statements.
No one says they know anything about the disappearance.
