Officials have identified the three family members who were shot to death in their Chisago County home over the weekend, and they also disclosed that a "person of interest" in the shootings was found dead elsewhere a day earlier.
'Person of interest' in fatal shooting of 3 in Chisago County home is found dead elsewhere
The Sheriff's Office released the IDs of the homicide victims as a couple and their adult son.
Found dead Sunday morning in their Fish Lake Township home on Brunswick Road were Darrell J. Mattson, 73, and Denise L. Mattson, 68, and their 47-year-old son Kirk P. Mattson, according to the Midwest Medical Examiner's Office.
All three suffered "multiple gunshot wounds," Justin Wood, chief deputy for the Chisago County Sheriff's Office, said in a statement Tuesday. The gun used to shoot the three has not been found, Wood said.
Wood did not identify the person of interest in the shootings. He also did not specify where the person died.
He said the Hennepin County Medical Examiner's Office, which investigates deaths in Hennepin, Dakota and Scott counties, will release the cause and manner of that person's death.
"Investigators working the case continue to believe the Brunswick Road shootings were not a random incident," Wood said.
In a separate statement on Facebook, the Sheriff's Office said: "We recognize the need for answers and calls for justice when an incident like this occurs within our community. We appreciate everyone's patience as we continue to investigate, and the members of this Office will continue to work diligently towards finding those answers you seek."
The returns were filed on behalf of themselves and others, according to federal prosecutors.
