The Örebro District Court found the 40-year-old guilty of attempted murder and sentenced her to psychiatric care. The National Board of Forensic Medicine (Rättsmedicinalverket) said that the woman was suffering from a severe mental disorder when she tried to kill herself along with her two children earlier this year.
The incident took place in September just outside Örebro. In court, it was revealed that the woman opened a liquefied petroleum gas cylinder in the car, which sparked an explosion when the gas was ignited inside the vehicle.
Both children, who are of elementary-school age, suffered light burn injuries to their faces as did the mother. The verdict stated that it was purely a matter of luck that neither the fire nor the explosion proved fatal.
The mother had previously written a letter expressing her desire to die along with her children, stating that they "should go with her".
In an earlier court hearing, the woman admitted that her intention was to kill her children. She agreed to undergo a mental health review, which concluded that the woman ran a high risk of relapse.
It was her second violent brush with the law. When she was 14, she shot and killed her parents but as she was underage, she was not sentenced for the killing.
Swedish social services are currently caring for her children.
