UPDATE 4:00 p.m. Tuesday, March 17

Lake County Sheriff  Don Bell has released the identities of the deceased in the murder-suicide investigation in Polson.

They have been identified as:

Matthew Alan Pruchnik - 49 years old

Liam Bradly Pruchnik - 7 years old

Levi Kazio Pruchnik - 5 years old

Though an investigation is still underway, Bell said it appears Matthew Purchnik, the father of the children, intentionally killed the two children and himself by carbon monoxide poisoning in their home on Lakeview Dr., possibly on Friday, March 13.  It is suspected that the motive is related to an impending divorce and custody dispute with the mother of the children.  Deputies had arrested Matthew on charges related to domestic violence back in August of 2017.
