Authorities are investigating what they call the "suspicious" death of a 47-year-old Makinen man.

The Midwest Medical Examiner's office ruled the death a homicide.

The St. Louis County Sheriff's Office said deputies found Frank Gerald Meyer dead at 1 p.m. Tuesday at a residence at 3316 Curt Lane in Makinen "under suspicious circumstances" after responding to a 911 call for a welfare check.

The Minnesota Bureau of Criminal Apprehension is assisting the Sheriff's Office with the death investigation.

Makinen is southeast of Eveleth.

Investigators are waiting for preliminary autopsy results from the medical examiner.

Anyone with information is asked to call the BCA tip line at 1-877-996-6222.
