I huvudet på en gärningsman - Season 2

Outwardly, Ragnar Nilsson seems to be a completely ordinary guy. At the same time, he is something of a recluse. When the police are called to his home one day in May 2010, they find three people brutally murdered.

In 1995, an 8-year-old girl is raped on her way home from school. The case then remains unsolved for 25 years. But when the case approaches the statute of limitations, the police suddenly make a breakthrough in the investigation.

A lone wolf determined to kill. During 2018 and 2019, the 20-year-old commits several assaults on people walking in Sollentuna. Excited about what he has done, he calls SOS to brag.

A woman calls SOS that her partner has suddenly become ill, whereupon he is rushed to hospital. It will turn out that she tried to poison her partner - and it's not the first time either.

The 23-year-old man had the future ahead of him, but after a party night, he abuses and rapes a girl. He is sentenced, but after serving his sentence he will continue to commit similar crimes.

Outwardly, the 30-year-old con man had it all. He was handsome, charming and successful. But it was all just a hoax. Instead, he exploits people to access their money in order to live in luxury.

The story of the two pedophile brothers was discovered at the beginning of 2017. During 15 years, they have preyed on several children, when the police later search their home thousands of pictures and videos are found.

In July 2008, the then 25-year-old Varg Nielsen writes in his diary: "soon a murder. know who, when, how". Two days later, he meets a 23-year-old mother of young children and murders her with 40 stab wounds.
