The victims of the double homicide in west-central Minnesota on Tuesday morning have been identified.
The Otter Tail County Sheriff's Office announced that Denise McFadzen, 42, and her 21-year-old son Dalton McFadzen were killed in the incident.
They died as the result of "homicidal violence" at their home in rural Perham.
In custody currently in connection with the double killing is a 21-year-old man from Pine River, about 60 miles east of Perham.
He has not yet been formally charged, as police continue trying to unravel the motivation behind the killing.
Valley News Live reports that the two were found dead in Gorman Township, 8 miles north of Perham, in a home at the end of a long gravel road.
The TV station spoke to a man identifying himself as the husband and father of the pair who died, who said he's "still trying to figure out what happened."
A GoFundMe page set up to raise money for the victims' funeral describes them as "the kindest, caring, loving people you would meet."
It also says "they were kind enough to let someone in their lives without knowing the end result."
According to the Forum News Service, court records show the suspect was declared mentally ill by courts in 2016 and was hospitalized after threatening to kill his own mother.
He was found mentally incompetent to stand trial and sent for treatment for schizophrenia, with possible attention deficit hyperactivity disorder and personality disorder.
