RED LAKE — The FBI confirmed it is investigating a fatal assault on Red Lake Nation — the second death investigation there in the span of a week.
The death occurred Tuesday, Aug. 11, two days before a shooting death involving a Red Lake Tribal Police officer also under FBI investigation.
The FBI confirmed in an email that the agency and the Red Lake Tribal Police were investigating the death of 60-year-old Jeffrey Brun of Red Lake. According to his obituary, Brun died at the Sanford Health-Fargo hospital. His death was reportedly from injuries suffered in the assault. A wake for him began Monday.
"Jeff was a kind, caring, generous, happy-go-lucky dude that will truly be missed, always loved and never forgotten," the obituary states.
No additional information on the investigation was available Monday.
Separately, the Minnesota Star Tribune reported the person shot and killed by Red Lake Tribal police Thursday was identified Saturday by the FBI as 39-year-old Matthew Scott Beaulieu Sr.
The FBI stated Red Lake Tribal Police responded to a report of a person, later identified as Beaulieu, firing a gun in a residential area Thursday morning. An officer fired his weapon at Beaulieu, who later died.
The Red Lake officer was wearing an activated body-worn camera during the incident, which remains an active FBI-led investigation.
