GRAND FORKS, N.D. (KFGO) – Grand Forks Police say all evidence points to the mother of three children as the person responsible for their murders.

The bodies of Astra Volk and her children, a 6 year-old girl and 10 and 14 year-old boys, were found last Thurs. morning in their home. Autopsy reports also support the determination that Volk shot and killed the children before shooting herself to death.

Early in the investigation, police said they were not looking for any suspects and there was no threat to the public.

Volk, who had a history of mental illness, had been having financial difficulties that may have been the result of medical bills.
