Legal boundary: the identified attacker died while the assault was being stopped, so he was never tried. The finding of lawful self-defense concerned the surviving father and son; it was a prosecutorial disposition, not a murder conviction against the deceased.
The pre-dawn attack
At about 5:30 a.m. on 21 August 2022, police received a report that shots had been fired inside a home in Blönduós, a small community in northwestern Iceland. Brynjar Þór Guðmundsson had entered the residence with a shotgun.
He shot Eva Hrund Pétursdóttir, who died, and her husband Kári Kárason, who was seriously wounded. The couple’s son and his girlfriend were elsewhere in the house. Reporting described the gunman as a former employee of Kári.
Stopping an ongoing assault
The son confronted the attacker. The available reporting said no firearm was used against Brynjar and that his death was not self-inflicted. Both the injured homeowner and his son later held formal suspect status while investigators reconstructed how the intruder died.
The distinction between arrest, suspect status and guilt is essential here. Police released the people detained after questioning and did not seek continued custody. Their status enabled investigation of a death at the scene; it did not establish criminal wrongdoing.
Earlier warnings
Later Icelandic reporting said authorities had previously received reports involving Brynjar and a firearm. Police had confiscated a weapon from him, though he held a firearms licence. Vísir’s account of the prosecutorial decision also referred to two reports that he had been near the victims’ home and neighbourhood with a shotgun roughly two weeks before the attack.
Those contacts form part of the documented lead-up. This dossier does not turn reported mental-health difficulties or prior police contact into a medical diagnosis or a complete explanation for the crime.
The self-defense decision
On 1 March 2023, the district prosecutor announced that no charges would be filed against the father and son. The office concluded that their actions were necessary to repel an unlawful attack that was already underway and did not clearly exceed the danger the attack presented.
That conclusion applied Iceland’s rule of necessary defense: conduct that would otherwise be punishable is lawful when required to resist or avert an ongoing unlawful attack, provided the defensive response is not manifestly more dangerous than the threat justified.
Review and final disposition
The attacker’s family challenged the decision. In May 2023, Iceland Monitor reported that the decision to close the case on necessary-defense grounds had been confirmed. No prosecution followed.
The criminal event is therefore classified as closed with an identified deceased attacker and a reviewed self-defense disposition for the surviving family members. It is not described as a conviction, acquittal after trial or unexplained double death.
Community impact
The attack shocked Blönduós. Municipal leaders held a public meeting, the local church hosted a support gathering and Icelandic Red Cross personnel travelled to the town. The response reflected the effects of a violent home attack on a community where many residents knew one another.

Frequently asked questions
Was anyone convicted?
No. The identified attacker died at the scene, and the surviving family members were not charged because prosecutors found their response lawful.
Why is the case considered closed?
The attacker was identified and the legal question surrounding his death received a formal, reviewed prosecutorial disposition.
Does self-defense mean the original shooting was justified?
No. The self-defense finding concerned the force used to stop the armed intruder, not his killing of Eva or wounding of Kári.
