Farther north, another blaze killed a 77-year-old woman.
Authorities are investigating a fire at an Anoka apartment building that claimed a man's life early Saturday.
According to Anoka police, crews were dispatched to an apartment building at 3030 6th Av. N. at 4:17 a.m. Saturday.
When fire and police personnel arrived, they found heavy smoke pouring from one apartment unit. They tried to enter the apartment, but they were unable to do so because of the heavy smoke, according to a news release.
Firefighters eventually found the victim in the back bedroom of the apartment. His identity has not yet been released.
The fire is under investigation by the state fire marshal's office, the Midwest Medical Examiner's Office, Anoka police and the Anoka County Sheriff's Office.
About 10 hours earlier, another fire killed a 77-year-old woman in Canyon, northwest of Duluth in northeastern Minnesota.
Florence Loraas, 77, was found dead in her home after the fire was reported about 6 p.m., according to St. Louis County authorities.
The fire's cause remains under investigation, but foul play is not suspected, authorities said.
