Kim Marie Johansson

Kim Marie Johansson (born Karl Kristoffer Johansson, ) is a Swedish convicted murderer who killed and dismembered Vatchareeya Bangsuan, Johansson's ex girlfriend. On 22 January 2014, she was sentenced to 14 years in prison, although the sentence was reduced to 10 years on appeal later that year.

Murder of Vatchareeya Bangsuan On 7 May 2013, 20-year-old Vatchareeya Bangsuan went missing. Two weeks later, body parts were found scattered in the forest.

It was also learned that Johansson had killed and cut up a pet dog, its dismembered body found scattered in the woods of Gammelängsberget. The town was shocked and residents protested at numerous public demonstrations. On 23 May 2013, Kim Marie (then Kristoffer) was arrested. On 22 January 2014, the court imposed a sentence to prison for murder on the 22-year-old Johansson who was sentenced to 14 years in prison, although on appeal later that year the conviction was downgraded to manslaughter and the sentence was reduced to 10 years. Johansson had 34 formal warnings for refusing to work and unauthorized possession of tablets. Authorities said Johansson displayed a strong interest in weapons, war, and explosives and had diminished emotional functioning, with an inflexible thought pattern, vulnerability to stress, and difficulty in social interaction. This meant that Johansson moved from a Class 1 maximum security institution to a Class 2 lower security institution with women.

At that time she was reported to the police for threatening to kill a prison guard.

In 2022, four young men were charged with beating up Johansson, but were acquitted in court.

In media A documentary about her case, In the Head of a Murderer – Kim Marie Johansson, was shown on TV3 Dokumentär.
